Dual egglofter. Ya scallywag! Blimey! 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, shiver me timbers, because t' contest got rained out. Ya scallywag! Blimey! 24mm motor mount. Aye aye! Blimey! Finish is Rustoleum 2X gloss white and black.
