Glad it worked out for you.
You wouldn't want me to build a house for you but I did spend years building wooden canoes and kayaks.
I learned real fast that very hot water allows the strands in the wood pull farther with no fractures.
Drying it bone dry will allow it to take a set.
Remember when your working with thin wood like this you can feel a lot of heat on the other side when using a heat gun but you can still have moisture in the pores of the wood so make sure it's *BONE* DRY*
Have fun flying the plane
