DX6i mixing

[Max]

I have a similar issue. I get full throttle forwards but only about 25% throttle backwards on Binky. Thinking of buying an external mixer, I already have one from The Robot Market Place, XR1... i think

I would check your travel adjusts, navigate to travel adjusts and check all the numbers are at 100% then move each stick forwards then backwards then left then right to make sure the values don't change, I have problems before whe I had a Travel adjust in direction and not the other.

With my dx6i I haven't had any problems with the mixing.
