You'll really like the PT-40 when it is finished. Several have flown at our field and they fly really well. My PT-60 is very similar, just bigger.

You'll notice in the manual that they describe two ways to build the wing. This is on page 4. If you will have an instructor when you start flying, you should build the "B" version of the wing. The "A" version has so much dihedral angle that the wings look very much like a flying "V". In the least bit of crosswind when taking off or landing, the plane tries to turn over. The "B wing" handles wind much better.

I built the "B" wing and my plane is great. It's very stable but will also do basic aerobatics easily. The manual almost makes the B wing sound scary, but it's nothing to be afraid of. One of our club members built a PT-40 with the A wing. He bought a wing kit and built a B wing after two trips to the field because the A wing couldn't handle the winds we were having this summer.
