Oh that I don't know TC.
Higher end radios, as you probably know, can have "curves" to match a stick to a desired action. For example, I have "cyclic" and "throttle" pitches in my radio (T7C). They are both generated off of the same stick, but are output on different channels (3 & 6 I believe). so I get an idle throttle at center stick, and the throttle increases both directions of the stick. The cyclic has 0 pitch at idle (hover), and gets up to +8 stick up, and -3 (beginner) stick down. Different idle curves give different curves. The 3D flyers go +10 and -10, for example. That could be idle-up2 (different pitch set).
So you might look for this ability.
Don't know if that helps or not.
Thanks for the response, but you missed the point of my post. I am pretty sure that my RC plane transmitter will work with an RC ground receiver because I have several Spektrum BR6000 robot receivers that are essentially ground receivers so that is not the issue. The issue is, what does the throttle output of the RC ground transmitter look like? Is it linear from 1.0ms to 2.0ms like with a RC plane transmitter or does it split the range to allow for the braking function with neutral at 1.5ms? That is the question. I am hoping that I will get an answer here and not have to do it emperically.
