I did not build it from plans, a friend did and crashed it so bad he was sure it could not be rebuilt. anyway, I took the pieces, put them back together and powered it with a Magnum .91 4 stroke. It is now one of my favorite planes and is a superb flyer. The only change I would make is to put a 1.20 on it as, since it gained weight in the rebuild, will not hover with the .91. It will land at a walk, flys hands off inverted with no down elevator required and will do most of the manuevers I attempt except for the tumble. I think you will love it. Just be sure to keep the wing incidence as per plan, a slight variation in the upper wing incidence can transform a plane from a dog to a pleasure to fly.
