Use channel 8 to fix the aileron drift, or channel 7 for elevator drift.

Go to Model menu -> Trims
Then configure like that (mode 2):
(why 3.3 step ? because the stock tx has 31 trim steps on each side, 100/31 = 3.22)
Then the trim switches will set the protocol trims

I found that H trim direction is inverted, I'll fix it in code later, but first check that it works for you please.

No, that's not required, I had a look at the mixer output, trims don't affect aileron & elevator channels when reassigned like I did.Durete wrote: Goebish, I guess you need also to configure the mixer as complex on aileron/pitch channels, and select "No trim" for these channels.
Default simple mixer is fine.
