Hadn't commented on it before, but I think it's a shame when your transmitter costs ten times what the plane does.

Haw.

Do you have a CAD system on your computer?
I do all my designs on CAD anymore, it helps me a lot

Status: offline 		Here is a different way to scratch build. I started with a large foam block and some CAD DWG's that a friend and myself made. I plotted out the top and sideview, then made templates to hotwire the foam, then did all of the contouring by hand.

This will be a plug that I will pull a mold off of and then layup the actual plane.

What thickness and what density of balsa are you using? What are adhesive are you using between the layers?

With four layers you could probably use 1/32", 4lb contest balsa up to 35%.

Wow, great idea!!!
