Hollow Motor Sticks

Has anyone tried to do this? What have been your experiences? Is there any information that would help? Thanks.

This is a bit common in free flight airplanes. There are several sites that tell you how to roll one. My luck has not been as good as using light weight balsa with a kevlar truss to withstand heavy rubber and winds.

I am assuming you are doing kevlar truss of the Freedom Flight kit? What actually failed when you do that? I did not even add the kevlar support because I found a very light balsa motor stick that can withstand the regular rubber full winding. The balsa piece I found for motor stick was 3/16 x 3/8 x 12 inches and it weighs about .7 grams. We got down to about 3.1 grams with that motor stick.

I guess you are having a hard time getting down the 3 grams?

What would be a good diameter for the motor stick?

I tried it and I didn't succeed
