Got a guy at our club that has an OS 120AX he just put in. He flies it quite well and it will do what ever he wants. He was still breaking in the engine the last couple of flights I saw, so it was running pretty rich.

The plane seemed to balance fine as this guy is very particular. He spends quite a bit of time getting everything dialed in the way he likes. Landings were also a non-event. Plane came in smooth as silk.
