I really don't remember how much time went into assembling the Cermark Pitts. It went together well, but the modifications that I seem compelled to make took a little time....I also had to wait for some items that I could only order after the model had arrived. It didn't take very long though.

I think that as responsive as this model is to aileron input two servos and couplers would be fine. The Saito 180 is kind of heavy, and it is more than enough power. A 120 4-stroke or maybe even a 1.08 two stroke would be enough power. A lighter model would surely fly better as the Pitts is just like it's full scale counterpart in terms of it's high wing loading.

It is a real kick to fly though, and an aerobatic biplane with that Saito 4-stroke sound is tough to beat.

If you get another you will not regret it. Lots of fun and a Pitts always draws a crowd....
