I have a pretty good handle on radio programming, or so I thought. I've used a Futaba 8U Super for several years and just bought a 9C Super (which is much easier to program). I've used the mixing capabilities to clean up my knife edge flight, counter the pitch affects of deployed flaps, etc..
But setting up the throttles on a twin has frustrated me. When I set up a twin on my 8U, I couldn't get the mix to work properly and ended up using "throttle needle mixing" to get the two throttles to work CLOSE to in unison. I just tried it with my 9C and couldn't get it to work properly.
I used a simple, linear mix with Channel 3 the master and Channel 8 the slave. I nulled the control for Channel 8 in the Aux channel menu. In the program mix 1 menu, I have 100% on both the arrow-up and arrow-down boxes. "Link" is off and "Trim" is on. 0% offset.
The end-point, sub-trim and trim settings for both channels are untouched at
100%. I haven't set up any idle down or throttle cut yet; they are default at "inhibited".The slaved throttle moves in unison with the master until about 75% throttle, when it stops while the Channel 3 throttle continues to open. This is the same problem I ran into when I set up a twin on the 8U. There is no information in either manual regarding this. The Don Edberg Futaba 8U book and the Futaba 9C website FAQ didn't mention it either.
Am I overlooking something?
I may very well dream about smashing both radios with a big hammer tonight as I sleep. :-)
Thanks for any advice, desmobob
