At almost 400 sqin wing area and ~30ozs it should be a good candidate. Keep us posted...

Simple Bipe


We are building two of them one with the standard ply peices and another with traced balsa, Im doing the ply and a friend is doing the balsa. I have drilled as many litening holes as i can and its still heavier than the balsa fuse with no holes. It should be interesting.

Sounds like a 10-cell project to me.
