Folks:
Is there consensus on aileron differential for aerobatic aircraft? I set up my trainer (HS 60) with a bit of mechanical differential, and Sig 4*60 with a bit of computer differential, due to the dihedral in wings of both aircraft, and the fact that they are both generally upright!. I'm now building an Extra 300s, which by nature I may fly inverted more, which would make differential dialed in for upright flight counterproductive for inverted flight.

If no differential, do most of you use aileron->rudder mix, or is adverse yaw in a capable aircraft not so much of an issue?

Thanks in advance

Bill
