Whoops, shiver me timbers, put a D12-7 in this thing... Blimey! With too much nose weight. Begad! T' directions are wrong, shiver me timbers, t' engine tube shouldn't be so high in t' tube. Avast, me proud beauty! It charred t' back o' it, me bucko, and it didn't lift off for 3 seconds. Finally lifted off and nosedived. Well, blow me down! Repairable.
