I Built a Smith Mini acouple a years ago, my first kit build. Followed plans exactly. When I took it out it's first year the torque roll to the left got me a couple of times and ended up having to rebuild the lower wing. NOW, I put 2 degrees of right thrust into the motor and with the OS 52 Surpass she takes off nice and level. It does baloon some on throttling up but I can live with that . Just a real pleasure to fly and is cute as hell.
