Maidened my plane last week and it's been a handful. It's hit the ground 3 times so far without me telling it to! Having trouble getting the OS 55AX to run reliably, and the plane is definitely porpousing and climbing out of dives - might be too tail heavy (balanced perfectly at the 100mm point).

I also noticed the stab has 2 degrees of incidence, and the wing has 0. Is this consistent with anyone else's?

After I finish up some minor repairs I'm going to try to hack off some weight from the tail. I've tried a 13x6, a 12x6, and a 12x8, but again have not been running right so still need to experiment. I wasn't happy with the really high rpms of the 12x6 though.

I ended up with a tank just under 12oz.
