Calling RC model plane builders
 

To practive my CAD skills I am going to make drawings of a Polikarpov I-16.

I need you guys to give me advise on materials for the balsa sections.

For starters I am going to go with 4 channel, fixed u/c.

I have some good 3-view drawings so anyone who wants to review the drawings for me is more than welcome.

Since nobody else has answered, I'll give it a shot:

What exactly is it you are wondering about regarding the balsa?

By the way, don't forget the thrust line adjustment on the forward bulkhead where the engine mount will go, people often overlook that when they draw their own plans!

:D Chock
