Is the Cermark Pitts that bad?
I am still flying mine. I enjoy the aircraft very much. Very stable, friendly, and tons of fun. I have flown mine with an OS 120 and a Saito 150. It flys wonderful scale aerobitics.
If you go with a large motor such as a 150 make sure you beef up the engine mount. I would do this with any engine.
As far as I know Cermark has sold out of them. I am not sure if they are going to produce anymore?
