I have my blades set at 71.4 with the Rotax 912 engine. Performance matches Van's published figures and engine/prop run very smooth without need for dynamic balancing.
I've tried different settings, but agree with Piper J3...71.4 works best (at least for me). Both blades dead on..is running super smooth! Digital level is easiest...as you set reference angle as per instructions.
