Hi there,
Here is my update for the Pitts too. I had my test flight last week and it was beautiful , very peaceful flier. I have powered it with a os70 4 stroke and it balances the plane at 3.1" from the LE of the top wing.

My Ailerons are at 50% throw so its not twitchy and flick dual rates for a sweet roll. The plane will not knife edge without a lot of aileron mixing so dint get to try that

The os70 is ideal power for it and not too powerful. The plane has ok sink rate and will land slowly and smooth. I also had a dead stick and knocked the LG out taking the support out from the fuse. I guess if it had been stronger then it would have broken it. The LG does not flex backwards so it pulled it out.

Also a major mod I had to do was to have to reduce the length of the cabane struts by about 10mm ... yes i had to cut them and drill them again as the present length if put just wouldnt fit. I am surprised as i did not hear anyone else needing to do this mod.

Other than that I would say this is a BEAUTIFUL PLANE. GET IT and enjoy

Cheers
KJ
