I have a 1/4 scale cap that requires a lot of up mix to the elevator for knife-edge flight.

as the cap comes in to land and slows the nose is high (tail heavy on purpose..... no mix on)

with this mix "on" it seemed to make this problem even worse (obviously).....I changed the mixes to a switch (had role coupling from the rudder also, had that correction on the same switch).

I think it helped with a smoother more predictable landing when the switch was "off".

I also experimented with having this switch "on" or "off" during hovering/torque-role. I have not yet reached a conclusion as to whether it helps with the torque-roll to have the switch "on" or off."

ps....Great Planes position on this issue is to have the corrective mixes ***on at all times***
