RE: Airsail Chipmunk build. Need advice.
I built this model 3 years ago now (it was a my second airplane). It is a really great kit, and flies extremely well. I used to fly it using a 46FX, which was enough power, and enough for mild aerobatics.
I stopped flying it since the engine and electronics are now in a new plane, but I just ordered a new fiberglass cowl 'cause I miss flying it (the plastic one was damaged).
If it helps, I still have a website up where I detailed most of the construction with lots of pictures.

Note, I never actually finished adding comments to this webpage, but all the pictures are up.
