Dual egglofter. Well, blow me down! Built for an informal duration contest, nay that t' design or construction made any concessions t' duration other than bein' wide enough for a big parachute; didn't matter, anyway, arrr, because t' contest got rained out. Aye aye! 24mm motor mount. Ya scallywag! Finish is Rustoleum 2X gloss white and black.
