Since you mentioned its windy where you fly I would go with the PT-60. I had the 40 sized version and it was one of the funnest planes I have owned. But the Krafty 60 of Aircruiser 60 would also be good and maybe just a little better in the wind. I emailed Bluejay models about a week ago and asked when they might have the 60 size aircruiser in stock but never got a reply. I have the Krafty 60 in my attic now.

A GP Big Stik 40 or 60 would work with your engine. I have the 40 with a TT 46 pro on it. Excellent airplane. I learned to fly with a Little Stik. So don't think you have to have a flat bottomed wing to learn to fly.
