I agree with tande plus the Cessna looks terrific! I disagree on the engine though. Mine flew very fast and had great vertical with an OS 61 FX turning a 12x6.

I have also heard of a couple of wings folding. In every case, the builder had tryed to sand the mold lines off the leading edge of the wing. Doing that weakens the leading edge and a very hard pull on the elevator can cause it to split. The solution is to simply ignore the mold lines on the leading edge of the wings and tail surfaces. They are hardly noticeable and they don't mess up the airflow over the wings.
