That does not happen when flying w/ sticks and pedals. I start flying with mouse when I see evidence they were used in WW2... 
Buy me a stick and track IR and Ill use it, or ill keep flying with my mouse with my 15$ a month.
Why not just use the auto-takeoff feature? 
Do you have combat trim enabled - affecting/chasing the level of fine control needed at slower speeds until torque is built up?
Auto take-off is for sissies, plus it doesn't work too well with jets.
This issue has nothing to do with combat trim or trim at all. On the ground my roll and yaw are linked on the same axis because hitech decided it was a good "feature" for newbies in Aces High 3 but leaves no way to turn off this annoying "feature" for the rest of us mouse users. All im asking is a way to turn this off in the settings so mouse control on the ground worked like AH2.
Much like the lack of soundpacks now because the sound system from AH2 was ditched when it wasn't broke, this is another problem I have with Aces High 3 vs 2.
