Oh it is a gem in the air, easy to fly and yes many traits exist that resemble the Cub, like the adverse yaw isue. The plane has a LOT of drag and needs power to do aerobatics. Remember that the real plane this one is modeled after was designed for doing competition aerobatics. I decided I wanted to be able to emulate that ability and considering the weight mine came it at the 1.60 was appropriate. While it might sound like overkill it really isn't, at least in my plane. At full throttle the 1.60 has good vertical and pulls the C-pro through the nicest loops you have ever seen. Due to all the drag the plane won't fly fast even with the big 2-stroke at full power. As for torque rolling it, the plane doesn't have nearly enough rudder to even think about trying that maneiver at my skill level.

I did a lot of reading before choosing the engine for mine. The few info sources I found said that they would like to have more power since their planes were "anemic", and they had 1.50 four strokes on theirs. All that leaves is the 1.80 Saito and the 1.60 OS or the Moki 1.80. I got mine solely based on the cost, with slimline pitts muffler about $300.

I think it all depends on what type of flying you like to do and what you intend to do with the airplane. With the 1.60 belching a nice big exhaust trail and inverted 5 feet off the deck comming down the runway, my C-pro is a real attention getter and crowd pleaser.

Any way wou cut it the plane is great fun and chances are you will be the only guy at the field with one of them.
