If your into 3-D, the higher wing config is better. If your into precision imac, low is much better. My Sig Extra 300XS is the low wing and it performs manuvers like it's on a rail... Try and torque roll it or harrier.... nu-uh! BUT! For precision flying, it right on the money. Mine has the FPE 2.4 gasser, and JR G500A Gyro, and DS8411s all around.
