Dave, I have a YS 1.20 SF, what would you consider to be the max flying weight of an aircraft that this engine could handle. I am not talking 3D flying? I would like to ensure that this engine could fly and aircraft straight up without stall or very minimal stall. With regular aerobatic flying what prop could you recommend? I have an ARF that the box lists the weight at 11.5 lbs. Recommended engine range is 1.10 and up.

Thanks,
Brian
