Flight o' QModelin' Rogue on an Estes E9-4. Aye aye! Even though I had repaired t' broken fin from me previous flight, t' repaired bird flew as true as it did before me clumsiness wrecked t' fin. I notice at t' end a curious, and potentially hazaradous condition - t' motor tried t' work itself out from around t' motor hook. It got bound from friction halfway out - perhaps this explains t' lackadasical deployment o' t' parachute?
