Actual FAQ’s for RDS8000 Airtronics

Previously I posted asking all of you for some pertinent questions you want to know about 2.4GHz equipment.

After giving my speech about 2.4GHz radios at the Toledo Show, I could see I need to light a fire under this subject. So, I’m trying it out here first…I’ll throw up a few, then you all can comment and we’ll build this database up!

RDS8000 FAQ’s

1. Why 2.4GHz? Why not 5.8GHz, 900MHz, etc.

2.4GHz is in a open consumer band that has many benefits. For example:

-There is simply less ‘model airplane’ interference through the 2.4GHz band. Most interference from vibrating metal parts, motor controllers, brushless motors, etc. all seem to be under 100MHz or so, thus making 2.4GHz very resistent to typical interference in our applications.

-This band is becoming more universal world-wide. For the first time, we benefit from the development of big industry electronics. And while “over the counter” components do not really work on their own for our applications, there is some much great support and technology already in existence it makes for better and faster development of the technology adjusted for our application. So, there’s equipment and technology available world wide AND when our pilots travel around the world, more and more countries use this same band, thus making the radios useful without modification world-wide.

-The FCC rules are different! The band is designed around preventing interference, thus the radios are working to keep your model safe from interference. It’s a whole different way of looking at how to use digital technology to work for the user.

2. What is FHSS?

-This stands for Frequency Hopping Spread Spectrum. What is means, in effect, is that the radio frequency is actually jumping around all the time. The idea is if the radio is transmitting on a specific radio frequency for a moment that has interfering transmissions, by the time these radio waves might have an affect, the radio has already switch to another frequency. It happens several times per second.

3. Can the radio loose it’s unique code?

-The Airtronics RDS8000 is written such a way that the code cannot be lost.

4. What about antenna placement?

-Antenna placement is important. The two antenna portions (the last inch of what looks like antenna..the black part is just an extension) at the end of each extension must be perpendicular (at 90 degrees) to each other. But they can be right next to each other or far apart, that is up to you. Why the extensions? So that you can position the antennas away from wires, carbon fibre parts, etc.

5. What is the range?

-As near as we can tell, no one is claiming a specific range. Why? Because so many factors can affect range! We tested the radio side by side with other brands and found it to be as good or better. Our empirical test was run on the ground and we had over 4000 feet of range. As you may know radio range will be vastly less on the ground than it is in the air. Also, keep in mind that at 4000 feet, you generally can’t see a 60 size plane well enough to tell orientation. 40 size planes tend to disappear.

Ok, Here’s 5 to get started. Give me some more questions and I’ll answer them! We can build the FAQ for RDS8000 together!

  1. Alex Bong Says:

    Hi Mike, i have problem to use my RDS8000 on Phoenix Simulator via buddy/trainer cord, it’s simply won’t work, but my Futaba 6EXH worked. hope you can check whether RDS8000 2.4Ghz system compatiblity with Phoenix simulator?
    Thank you!


  2. mikegoesflying Says:


    Obviously we have no control over the design and thus compatibility of our radio with any Flight Simulators.

    However, your comments/requests sure seem pretty appropriate to me. Thus, I have contacted Phoenix to see if there’s anything that can be done.

    We’ll see if I get anywhere.


  3. HUGH NELSON Says:

    Hey mike its your old friend hugh. My pops just picked up a RD8000 2.4. were reading and learnign about i tnow. ! question we have is receiver battery. WE picked up a 6.0 volt XTM 1000 mah nimh (1 price was great) and were planning to use it. But upon reading the radios bible, it only mentions 4.8 volts. Are question is this.
    Can we run 6.0 volts on a 2.4 reciver or is 4.8 volts the max it will handle?

  4. mikegoesflying Says:

    Hi Hugh!

    6.0V is fine. The receiver is rated for 4.8 to 6.0V with no problem.


  5. Peter Says:

    Hello Mike, In regards to range check on RDS, I have control surface response in range check mode on transmitter up to 30 paces, after 30 paces signal loss is evident whether engine is running or not. My question is, will my plane be safe based on 30 paces as per manual?

  6. mikegoesflying Says:

    Yes, that should be safe. The range test parameters we list are the expected range on the ground.

    If you are unsure, do a full-range test.

    ON the ground, in a straight line, no obstructions, the plane should be able to be 1000 feet away and you should still be able to control it.

    You can also try removing the receiver. Is the range the same? Maybe the fuselage is interfering with the range. This would show it.

    And, please make sure that the two antennas are 90 degrees to each other.

    Anyway, if you meet the range parameters you are fine. If not, run a full-range test.

    If you are concerned, send it in or message me and we can discuss it further.


  7. Mark Says:

    Is the RDS8000 switches assignable for various functions? Are the channels on the Receiver assignable for various functions?

  8. mikegoesflying Says:

    No. The switches and channels are not assignable. This is a 200 dollar sport radio. Those types of features are usually found on more expensive (read that more expensive computer inside) radios.

  9. Felix Says:

    Hello Mike,

    The RDS8000 manual cautions the user about possible interference from other 2.4 Ghz radio controllers while the Futaba and JR manuals do not. Are Futaba and JR’s transmission schemes superior to Airtronics’?


  10. mikegoesflying Says:

    Felix, I am not sure which warning you are referring to. If possible maybe post a comment with a quote and page number?

    I am not sure what you mean by “schemes”, but if you’re simply asking which is better, I won’t answer. The bottom line is that I do NOT run down or say negative comments about my competition just to try to make ours look better!

    Our radio has proven itself, over and over, to be reliable even in very heavy-use situations. We have sold a ton of them and we’ve had tons of pilots across the country flying it several times a week in tons of different planes and environments. They all report the same. The radio is rock-solid.


  11. Felix Says:

    I just purchased and received my RDS8000 yesterday, and I am eager to give it a ride. Your confidence in the radio is certainly assuring. However, I don’t understand how one can miss the precaution at the top of page 13, note 3 in particular.

  12. mikegoesflying Says:

    Thank you for providing the actual reference. I can address your concerns specifically when I know what you are talking about.

    If you read through my blog, you will note I have discussed this repeatedly. What the engineers are getting at is something that no one talks about much which is saturation. It begins with these common mis-understanding about 2.4GHz: Many people believe that an infinite amount of 2.4GHz radios can be on and in use at the same time. This is NOT true. Spektrum flat out tells you their max number because they are using fixed frequencies. With FHSS this number can vary greatly according to environment/proximity to the other radios.

    For a worse-case scenario: Let’s say you’re at an indoor meet and there’s no control over how many people are flying at a time. You might have a very large number of people trying to use the band at the same time while all standing VERY close to each other AND flying very close to each other. This can cause RF overload (not just with our radio, with ALL radios in all bands… just no one talks about it from this point of view). Remember it is still a RADIO, thus physics of radio waves still apply. Somewhere along the way destructive interference will occur.

    So, if you try to fly in a place that is overloaded with radios (for example there are so many on that the DSM/DSS equipment will not even work) our frequency hopping system might “slow” and the plane will feel sluggish.

    Normally this simply never happens. So far not one pilot we have has actually experienced any type of RF overload.

    In the conditions of the tests we ran, we generally found that it was about 40 2.4GHz radios, all on at the same time, with everyone standing within a 20 foot radius (like you might have at an indoor event in the pits).

    If it is only Airtronics radios on, for example, you can have more than 50 in very close proximity use and they will all still work.

    If you are using other brands “only” the number varies between 40 and 50 generally speaking.

    However, when mixed, we feel the safe number in this environment (at least in our tests) seems to be between 37 and 40.

    Think of it this way, each company takes the available band, splits it up as they see fit, and then either picks a couple of fixed frequencies or starts bouncing around all that they have picked.

    So, even figuring that everyone is dividing it up differently, in the end you can still simply use all the “space”. And, the way they divide it up is pretty wide. We’re all still sharing a frequency band and truly an infinite number of radios cannot be in use at the same time.

    Remember, if you are using ONLY Spektrum, the number is somewhere between 39 and 43 (it seems that for maximum performance the number under 40, but due to their use of the technology up to about 43 or 44 will work “ok”). If you’re using Airtronics ONLY, the number is about 55. I am not sure of the other brands, but still you get the idea.

    Our engineers are trying to simply tell you that you can “max out” 2.4GHz band and that we do really share it with other consumer electronics. Thus, you still must use caution. Make sure your radio is working and responding properly before takeoff and if during the flight, it feels sluggish in anyway, land before it gets any worse.

    I am not sure how the other companies explain or don’t explain it, but it is the reality of all systems, not just ours.

    I hope this helps.


  13. Ryan Says:

    How far of range does the Airtronics RDS8000 2.4 ghz get?

  14. mikegoesflying Says:

    As I pointed out in No. 5:
    5. What is the range?

    -As near as we can tell, no one is claiming a specific range. Why? Because so many factors can affect range! We tested the radio side by side with other brands and found it to be as good or better. Our empirical test was run on the ground and we had over 4000 feet of range. As you may know radio range will be vastly less on the ground than it is in the air. Also, keep in mind that at 4000 feet, you generally can’t see a 60 size plane well enough to tell orientation. 40 size planes tend to disappear.

    ON the ground in perfect conditions, full range is 4000 feet. This means that in the air, it will be more. How much more depends on many factors some of which are simply beyond anyone’s control. And because 2.4GHz radio waves are so short, they are great affected by physical things that get in the way of the signal from metal to carbon fiber.

    It is important to note that most of these items only affect the outer reaches of the range. In normal use (1000 feet away or less for most power planes as an example), you’ll never test or see the end of the range of the radio.

  15. Mike Says:

    How’s it react on larger aircraft? (50cc+) Does the engine cause radio issues?

  16. Mike Says:

    Also, if you lose the “link” with the reciever, how long does it take to get controll back?

  17. Felix Says:

    Hi Mike,

    Okay, the receiver antennas are supposed to be placed perpendicular to each other. I guess it doesn’t matter whether the perpendicular placement is along the horizontal or vertical plane, or does it?


  18. mikegoesflying Says:

    Mike, The radio works fine with most ignition systems. Their interference tends to be well under 2.4GHz. Truly “loosing the link” has to do with outside radio interference, so the speed at which it “relinks” will be “as soon as the outside interference goes away”. I think you’re asking, however, about the reboot if the computer experiences low voltage. The receiver computer works down to below 2v so long AFTER the servos have stopped working, the receiver will still be working. Thus, there is no problem will low voltage on these receivers.

    Felix, other than the ends being positioned 90 degrees to each other, the position does not matter.


  19. Mike Says:


    I just got my RDS8000, test flew it today on a .40 trainer.

    Great system love the “feel” you get with it. Make you feel really connected to the plane. Gonna try it soon on one of my 50cc planes.
    Thanks for all the help,

  20. Roman Says:

    Hi, Mike.

    I’m very happy with my RDS-8000, rock solid system so far.

    Anyway, are you planning on developing a telemetry system, as other competitors are doing? (e.g. Jeti). I think this feature would suppose the Airtronics definitive punch, as the ability of real time control on remaining capacity in battery pack is imperative to us, electric powered flyers.

    Sorry for my poor English. Best regards from Spain.

  21. Rick Says:

    If I buy one of the 8000 will the receivers be compatiable with and if the 2.4 module ever comes out for the Stylus. And in you opinion on a scale of 1 to 10 how would the 8000 programming features compare to the Stylus. And will the rec. be compatiable with the new 10 ch. TX.


  22. Rick Says:

    I fly mainly sail with glide card.


  23. mikegoesflying Says:

    The new Stylus Module will be compatible with the current RDS8000 receiver as well as the new smaller receivers. The RDS8000 is a sport radio and does not have near the capabilities of the Stylus. If you need that type of programming, you’ll need to wait for the new 10ch


  24. mikegoesflying Says:

    The current radios will not have 2-way real-time telemetry. We are considering this for future models, but it is not part of the current models.


  25. Felix Says:

    Man, I love my RDS8000 radio. My previous FM radio does not even compare when it comes to control authority. Combine that with the peace of mind you get from the absence of shoot-down interference. What more can anyone ask for? A transmitter and 2 receivers for $229, only Santa Claus can give a better deal.

  26. Eric Says:

    I was looking into a rd8000 for use in a scale boat project where I need the use of several channels. I have been told 2.4 is fine for air or surface but have heard many horror stories of radio glitch and signals bouncing off water. I completely understand about obstructions does water have an effect on 2.4

    • mikegoesflying Says:

      The water/boat/2.4″thing” has to do with range and output.

      The RDS8000 will have no problem in your boat as long as the antennas are extended straight up above the water line.

      The RDS8000 is a full-range, high output (as compared to earlier surface radios). That is what makes the difference.

      If you want both sticks to “center” rather than having 1 stick that stays in position, get the “crawler” edition 751712 part number. Same radio, etc, just with the sticks configured so that they both center.


  27. Eric Says:

    so both antenna strait up out of the water no need to do the 90o
    would it help to have the receiver higher to get the antennas up a little more.
    Thanks for the clarification I’m sold especially with it coming with 2 receivers

  28. Ron Says:

    Will the RDS8000 bind with other manufacture’s 2.4 receivers?

    • mikegoesflying Says:

      NO, just like with PCM, the digital encoding is unique from brand to brand. IN fact I’m told that one company tried to make their radio compatible with another maker’s 2.4GHz radio and they were sued over the deal. It seems the encoding is unique, proprietary, and protected.

      The good news is that the servos are still interchangable and that can truly be the expensive part of setting up many planes (especially bigger planes with 11 high performance servos in them!)


  29. Alex Says:

    Hi Mike,

    what about LiPo for this unit?
    Or how to change Mode2 to 1 or M1 to M2.
    Or maybe backlight.


    • mikegoesflying Says:

      RDS8000 can use a Li-PO, no problem. There are many on the market that fit.

      Switching mode 2 to 1 requires “service”. End user cannot do it. However, we offer the radio on Mode 1 so if you want it mode 1, it’s available.

      There’s no backlight on the screen available.


  30. Alex Says:

    Co no need for any kind of bec or voltage regulator?

    ‘Service’, or if i’m too far away and postage will cost the price of Tx? What about ‘advanced’ users with iron in hands? (i have mode2, so i do not need mode1, just curious)

    Backlight, do you plan it for new 10ch tx?

  31. Ivo Says:

    Were can i buy Li-Po for RDS8000?
    12,5V (11,1) no problem?!?



  32. chrisbabe Says:

    Q: high voltage servos and rds8000 rx… how? is 7.2 volts okay for the rx??

  33. Jonah Says:

    Here’s wishing you a very happy and prosperous new year !

  34. Byron Bruce Says:

    Hi Mike,can the RDS8000 be used on an F/A-18 useing(tailerons) elevators that work seperatly of each other (like elevon on a delta airframe) while maintaining seperate rudder and aileron control?

  35. Franco Says:

    I’ve read through the comments above, don’t see what I am looking for.
    Here’s some background. I live just outside Washington DC. started flying in 1963, but post 9/11 RC flying in this area has become nearly impossible. I have many aircraft hanging in the garage, and have always used Airtronics radios and transmitters. I must have 20 servos of all shapes and sizes. There are 4 or 5 PCM radios. OK to the meat of my question. I want to retire to South Carolina and resume flying. I’m looking at the Airtronics transmitter packages, but for some reason they all say “Tx andRx” only… What gives? Will I be able to use my old servos? I would like to get the newest best FHSS Airtronics system, but what will I be able to salvage from Gliders, 1/2A models through .90 Saito 60 size stuff? I do not do helicopters, so what is your recommendation?


    • mikegoesflying Says:

      It’s a little complicated, but not too bad..

      Today Airtronics only sells TX/RX setups because the hobby is so diverse, a standard servo isn’t really standard anymore.

      The FHSS-3 10ch receiver will only work with digital servos. So, most likely it will not work with your old servos.

      HOWEVER, ALL of the FHSS-1 receivers WILL work with your old servos. These receivers are more affordable, are still full range, and have no problems with older analog servos that are in good working order.

      NOTE> You will need adapters. We use an industry-standard plug today. However, back when you were flying all the companies used a unique plug. So, you’ll need our old adaptor to connect Original Airtronics Servo to Z-connector receiver.

  36. Franco in Springfield Says:

    So from your account, I would need to find someone that carries Airtronics FHSS-1 radio and receivers.. ( I would want at least 2 receivers). I think I have some “Z” connectors.. or adapters, as I recall, the only difference is that + and – are not in the same place as the older Airtronics servos. For my flying, Goldberg gliders, big old slow (12 foot wingspan) German Hi wings, the likes of a highly modified Sr. Falcon do not need precision servo’s, what would a digital servo buy me?



    • mikegoesflying Says:

      Tower Hobbies, Hobby People (, A-Main Hobbies and Peak Electronics all carry Airtronics. There’s a list of dealers at

      The RX600 6ch receiver would be a great choice in all of those airplanes. And, unless the servo has a pot or motor that is failing, those old servos will work fine in the RX600. The adaptor plug is needed because the shape of the new plug is smaller than the old one, thus it isn’t enough just to switch the wires around.

      Digital servos are typically more expensive but deliver more torque, deliver it all as soon as the servo moves, and they stay in position when under higher loads (so there is less “blow back” when the wind on the control surface actually causes the servo to move). They are also more precise.

  37. sahil Says:


    can i use micro/mini analog servo on Airtronics 2.4ghz 10ch receiver ?

    or which analog servos work with the 10ch receiver ?

    • mikegoesflying Says:

      Most analog servos simply do not work with the faster frame rate of the SD-10G r10ch receiver. Analogs work fine with the FHSS-1 receivers which are also very affordable, but not with the 10ch receiver.

      I suggest you look at the new digitals from Airtronics

      These are all micro or mini sized and are all priced similarly to analogs in their category. They are all digital and will work great with the 10ch receiver as well as the other brands.

  38. Franco Says:

    From the pictures and descriptions, it looks like there is no proportional “6th” channel on the 8000. Am I totally snookered with Airtronics radios if I want a slider to operate flaps?

    Just for the record. Most of my R/C aircraft are equipped with flaps, not because our models need the extra lift. The wing loading for most RC airplanes is very low. However, a fowler flap arrangement where the trailing edge type of strip aileron is moved back and down makes approaches much slower and roll-outs are very short. Unfortunately, to make best use of these, slider control works best. Starting with 10% the aircraft starts to slow as air is squished through the slot. At 20% there is less braking or drag effect, and lift is enhanced causing a “Float” As you move rearward towards full (just prior to TDZ) the aircraft really slows.

    All of the above is best achieved with a slider since percentages are just an approximation and wind and weather preclude a set notch.

    This used to be a standard feature…


    • mikegoesflying Says:

      The RDS8000 does not have a proportional channel for flaps. It is a 3 position switch which is fairly common for radios in this price/type range.

      The SD-10G has the option of either 3 position flaps or proportional flaps or a mixture of the two. The radio costs more but is vastly more advanced in terms of mixing, etc.

  39. Franco Says:

    I have found another manufacturer that has a 7 channel 2.4 gig radio that has an optional setting that allows for proportional control of an auxillary channel. I’m not crazy about the location of the dial (trim) for the channel, but it is full range control. I am now checking to see if this unit will support use of the old servos that I have installed.


    • mikegoesflying Says:

      Just keep the 10 in mind. At 350.00 right now it’s a steal and it offers much more than just proportional flaps.. If you’re flying scale and want the extra features, etc, the 10 will serve you well.

  40. Alex Says:

    on i can see it for 450 and 500 usd (7ch or 10ch rx)

  41. Alex Says:

    Cool.. thank you (but no shipping outside)
    Why is eshop only, where is detailed info about products?

    • mikegoesflying Says:

      We’re having a technical problem with new software. will not be 100% functional with tech data, etc for approximately 90 days

      • Alex Says:

        It is a magento ecommerse software (chnge a default theme at least to be unique). Just add please tech info, please. OR gimme a try i’ll do it in less than 90day. Ok?

  42. Franco Says:

    I would consider the extra bucks for the 10 if it weren’t for one thing. You indicated that I could NOT utilize the older servo’s. This means planes like my Gentle lady, (several other old gliders), park flyers with micro servos, a bunch of special purpose designs, Falcon 56, Modified Sr. Falcon, all having servo’s and in some cases micro switches to run heated 4 cycle plugs, all would have to be re-servo’d and that’s where I choke on Airtronics. The pain ain’t worth the gain. Purchasing a “Z” connector is a nusainse, but I can swallow that. Buying all new servos is another thing.


  43. Jonatas Says:

    What the “throttle cut switch” do on a rc glow powered plane?
    Nice blog!


    • mikegoesflying Says:

      Over-rides the throttle and brings the throttle down to a position you set to either slow or stop the engine.

  44. Jonatas Says:

    Another doubt.
    Is this forum thread, some users reported a problem related to linking.
    Can i have “peace of mind” if a buy a new one?

    • mikegoesflying Says:

      We have had a few RDS8000 radios that had this problem. It has long since been resolved. If you do experience an issue with it our service center can fix it.

  45. Anthony Says:

    Hey Mike,

    I have an Airtronics RDS 8000 system and would like to purchase another receiver for it. Do you know which receivers are compatible with it? I am asking because I only need a four to six channel receiver.


    • mikegoesflying Says:

      All of the FH1 receivers will work. So, besides the 8ch RX that came with the radio, you can also use the following
      RX60 Park Flyer Receiver
      RX500 5ch Full Range Receiver
      RX600 6ch Full Range Receiver
      RX700 7ch Full Range Receiver


  46. Gene Lynch Says:

    Mike, I stumbled on this site last nite and have questions re RDS 8000. I am ready to buy it. I have not flown RC in 10 years, about the time AT went with the “new Z connectors”. I gave my almost new Spectra 7 to my son in Houston. I have lots of servos, 94631. Can they be made compatible with the 8k or do I have to give them to son also. Can you recommend high power battery packs for Tx & Rx. Thanks for listening,

    • mikegoesflying Says:

      Hobby People sells a brand call Hi-Energy. They have a 2200mAh pack for the TX and rx available.
      Connectors will either need to be changed or you’ll need adaptors. But yes they will work.


  47. Mike Says:

    Hi Mike,

    I just purchased an RDS 8000. My receiver is an RX600 which has only one channel for ailerons. What receiver do I need to enable me to use an independent servo for each aileron?


    • mikegoesflying Says:

      It is according to what functions you need. If you set up the dual ailerons using the flaperon function and then turn off the flaperons, you get channel 1 and 6 for aileron, thus the dual ailerons plugged into separate channels will still work. But you then do not have separate flaps anymore. Otherwise, you’ll need a 7ch receiver.

  48. Ben Says:

    Hi Mike,

    Im trying to figure out the full potential for my RDS8000 in conjunction with a powered acrobatic glider with ailerons, elevator and rudder.

    I want to achieve the following:
    – use of flaperons
    – triple rates for all control surfaces on a single switch
    – expo on rudder

    Whilst setting the flaperons is easy, Im stuck with the remaining two settings. I looks like flight modes and additional features on rudder are only available in heli mode. But when I try to abuse the heli mode on the glider, I dont have flaperons.

    -> Is there a way to use the flight modes in airplane mode? Beside the fact that rudder rate and expo cant be changed in plane mode, it also would make sense to 1. have more that just 2 rates, and to change all control surface controls with a single switch.


    • mikegoesflying Says:

      The RDS 8000 does not offer triple rates nor does it have assignable switches, also, it does not have expo for rudder. Flaperons or even a basic 4 servo wing is do-able, but the radio is not designed for some of the things you’re asking it to do.

      If you want triple rates and assignable switches, you’ll need an SD-10G.


  49. Zonuna Says:

    HI do, I am not sure if you still answer questions, if you do please help me.

    I have an RDS8000 (Sanwa) can i bind with Receivers other then RDS800(Sanwa) i.e other brand of RX

    • mikegoesflying Says:

      The RDS8000 will only bind with other Airtronics FHSS1 Aircraft Receivers. There are a lot of them to choose from. RX40, RX60, RX500/600/700 and the stock 8 channel. It will not bind with other brands.

  50. zonuna Says:

    Thank you Mike

  51. Vaughn Says:

    I just bought an rds8000 crawler radio to use for my various robotics projects . I’m not able to got the transmitter out of the HI TH alarm state after I turn it on (no matter how I move the throttle or trims) !!! Please advise , I hate to have to send it back as my holiday vacation is neer and I have a large tank project in progress.

      1. If you can’t make it work, I suggest calling service directly Monday morning. also, the service email is

      2. Try pulling the other stick down and see if that engages it. My guess is it’s in the wrong mode.

    Hi Mike,
    Any idea on this issue?

    I have two RDS8000 transmitters and reciently bought a trainer cable in hopes to help a few friends in the area with their plane and heli flying. I was setting the perimaters on the trainee transmitter to match the main transmitter, and was unable to complete the entire process due to a time restraint. I believe I just turned the transmitter off. A short time later, I was going to complete the process and I am unable to start the transmitter due to it being in “IDLE UP” mode. I was in the throttle curve process when I ran out of time therefore I am thinking I somehow set a perimater to a position that somehow makes the transmitter think the throttle stick is not set in its lowest position.

    It indicates “Idle Up—Basic” mode when powered on.

    Right and Left toggles up indicates F-MODE 1
    Right toggle in center position indicates F-MODE 1
    Right toggle in the down position indicates F-MODE 2
    Left toggle in the down position Blank (F-MODE 3)

    Will not indicate NORMAL MODE at all.

    Maybe a faulty “Normal, Mode 1, and Mode 2 toggle switch?

    Hi Mike,
    I have an RDS8000 and it works fine – two questions.
    1. Is there a PDF of the operating manual available? I’m afraid of dog, grandchildren etc. destroying the paper copy.
    2. I have found it difficult to source a second receiver here (in Ireland) and have arranged for my brother in Florida to get one. Its called a Sanwa RX841FS here, but the Airtronics 92824 seems to be the same in the US.

    If I buy your RDS air radio is it the same as the crawler/surface version?

    I assume I just need to buy the pieces to make the left stick self nuetral since they are both mode 2?

    Also if I want the left stick to self center going up and down and I want it to ratchet going left to right then could I just swap those pieces on the left stick.

      The Crawler radio is technically mode 1 and the gimbals have been modified so that they both center which requires parts and tech work.
