Flight of QModeling Rogue on an Estes E9-4. Even though I had repaired the broken fin from my previous flight, the repaired bird flew as true as it did before my clumsiness wrecked the fin. I notice at the end a curious, and potentially hazaradous condition - the motor tried to work itself out from around the motor hook. It got bound from friction halfway out - perhaps this explains the lackadasical deployment of the parachute?
