RE: GP T-Craft
I have one of these too and I love it. I put a Magnum 30 four stroke in it. It's not a lot of power, but it's definitely a good combination for the plane.
I used the Pacer canopy glue for all the windows and it's fine. I glued the sheets for the side windows on the inside, and it's held up well. If I had thought of clear Monokote, I probably would have done that; sounds like a great idea.
