When I brought this up a couple of months ago, consensus seemed to be lower wing and stab at 0 degrees, top wing at -1.5 degrees. That's the way I set mine up to start.

Unless someone tries to talk me out of it, I'll be setting the motor box at 3 degrees right, 2 degrees down. Motor will be a Brison 2.4 swinging a 20x8 Menz S.
