I currently fly 2 twins on a y harness with a Futaba 6XAs. I am waiting patiently?????? (with much anticipation) for the RDS 8000 I have on order. CAN'T WAIT TO GET IT!. thanks again Skip D Thanks Mike. I currently fly 2 twins on a y harness with a Futaba 6XAs. I am waiting patiently??????

Channel 8 could be set up for idle and high throttle positions using Channel 8 EPA's for one of the engines. Channel 3, the throttle channel could also be set for idle and high throttle operation using its EPA's for the other engine. This is done separately. Next you can use Compensation Mixer #1 to make Throttle the Master and Channel 8 the Slave. The Throttle to Channel 8 Mix would be set at 100%. Once both engines have been tuned for proper low and high speed operation, the Compensation Mixer switch, located to the left of the HOV-PI switch would be turned on and remain on. Both Channel 3 and Channel 8 servos would then respond to the Throttle stick. However, there is a major problem in trying to do this. The Throttle trim will only trim Channel 3! That is not a desirable thing if both engines are running too fast at low throttle when you are in the air. You could have a very unsafe situation since the engine that cannot be trimmed could cause the model to slew, turn or roll, and your rudder control may not be sufficient to correct the problem. Mike's comments: You can use this but you better be sure low-stick and proper trim is set! Jack actually does not recommend this setup due to his concerns about the trim. Because it's only a twin, it really might just be simpler to use a Y I talked to Jack (who runs the toll free Airtronics service no.)

Also I have a RDS and 2 receivers on order, can't wait to get it. Mike, On the RDS8000, can channels 7 or 8 be slaved to the throttle for twin engine operation??
