More heat, and don't be afraid to pull it as you heat it around wing tips and other round surfaces.

I have learned to get the edges sealed down
Make sure the edges are completely sealed!!!! YES YES YES!!!
If you are using Monokote, shoot the entire frame with a cheap hairspray. I use Aquanet....
The hairspray will seal the wood, but also helps the Monokote adhere to the frame.
My .02 cents.
