Cap,

I think you might have mulitple issues that are making your throttle so abupt on the low end, but once you set it up so it is mechanically just about right, then you might be able to improve it even more by using expo on your throttle.

I have a Futaba T7C and do have my throttle set to +25% expo.

before expo it seemed to me that I already had about 3/4 power while the throttle stick and carb were only at 1/2. And also there was almost no noticable power difference between 3/4 throttle and full throttle. My expo setting seems to delay the carb opening at low stick positions so I have more percision about idle speeds and the expo accelerates the throttle opening at high stick positions. At least with my set-up it seems to make the stick position better correlate to the actual power output of my engine.


EDIT: I just read Mikes post above. I see where the confusion is comming from. I will get out my manual and double check but I am quite sure that on this raido the expo setting for the throttle is not based on the center point like expo on Ail, Rud, and Elevators are. The expo for the throttle is based off the end-point, so it is designed to smooth out one end while accelerating only one end.
