Looks sort of like a stretched Odyssey Explorer and should be impressive off the launch pad. Use epoxy, when constructing, also C/A lamination to printer paper, will increase strength of balsa for composite motors and anything over E15, or take a chance shredding fins. Hint, hint, to decrease asymmetry, relocate the launch lugs closer to the BT55, by porting the nozzle and nose cone for through launch lugs and less rod whip at lift off.
