RE: Anyone using this GAS motor for pattern? ZDZ 40
I did in the Abbra two-three years ago. Weight was very close to 11 lb. You will need to be careful with weight. The Abbra with YS 160 is a little below 10 lb. I help a friend to put it together. I flew the plane two or three times. In my opinion, it will be OK for low classes but for Master the power could be a problem.
