I built a PT40 as my first plane. It's a nice plane but be careful, the directions "strongly encourage" you to build the "A" wing. So I took their advise and built the "A" wing. I was sorry I did... It has way too much dihedral. The ailerons would not even work. It turns fine with the rudder though. I ended up plugging the rudder into the aileron channel and it flew fine after that. In my opinion the "A" wing is fine for 3 channel, but if you want ailerons build the "B" wing. It's no big deal, you just use different joiners that Are labelled "B" instead of "A".

That plane is built like a tank... Very strong, very thick, plywood and balsa. It has VERY strong landing gear and can absorb some incredibly bad landings. Get some bigger wheels for it if you are going to run it in grass.

I ordered a new wing kit for it and was in the process of building a wing with less dihedral when I crashed it into a tree. The plane was undamaged but I accidentally broke the tail off trying to get it out of the tree.

It would have been easily repairable, but I haven't fixed it yet. I took the engine and radio out and bought a Tower trainer 40. I was ready to fly and it will take me awhile to finish that wing. I put the PT40 landing gear on the tower trainer too because it's landing gear really sucks.

The Tower trainer flies really nice and the ailerons actually work!! But is built nowhere near as strong as the PT-40

A PT40 with the B wing should be fine. Oh and by the way, put a 46 size engine in it. I had a OS40LA in mine and it was a bit underpowered. My tower trainer's even a bit underpowered and it is a much lighter plane.
