Three flyers at my field purchased the 48" version of the Great Planes Super Sportster electric.
1 used a brushless set up, 1 was stock with Nimhs, and the 3rd was stock on lipos.
All three suffered collapsed wings while in flight. [:@]It seems the ply spar only goes past the fuse sides by about 1 1/2" and then gets butt joined to a balsa spar which goes to the wingtip.[:'(] It's at this joint that all 3 wings broke.[X(] Reinforce this area before flying this plane.[sm=idea.gif]
