Wow. Thanks alot for the input. I was originally going to dedicae channel 1&6 for my aerilons/flaps. I have been hearing that flaps are not a neccesity in the model and thata seperate servo on channel 6 (proportional knob) is the way to mix fuel in flight.
As it is I wanted to keep it light but since I modified my F 16 for servos on each aerilon (mounted in the fuse) and a digital servo in the tail for elevator. (I didnt really like the nyrod's) I did leave a nyrod for nose steering and rudder.
As far as my engine I may be ok if I keep the weight under 12.5 lbs and since the plane has no drop tanks or missles, the airframe is pretty clean. Im not sure what off-the- shelf fuel to use. I broke the engine in with coo, power 15% synthetic. I was not aware of the science involved in fuel for a DF engine.
I am hoping K&B will make DF engines again and want to purchase something bigger I can afford.
All the articles I read from "older" RC mags say this powerplant is sufficient to move the F 16 , heck they used to use a .61 and that worked. Well Thanks for the advice on the mixture control( I already have the remote arm) and will use channel 6 and just make those aerilons work on a "Y" harness.
