Was having so much trouble trimming. After the previous post I thought… I should look into this again. I described (in another document, that I referenced) how I mapped the buttons and silly me, I assumed they were mapped that way… they weren’t! So I remapped them like below and voilà (wa la)… it works. The important keys are 8 and 6 for up/down pitch and 14 and 15 for trim left/right.
Adjusting the pitch has been an issue for years. And the main problem was they were mapped wrong!
