Rocket immediately took off at near a 90 degree angle after leaving the 6' launch rail.and veered off into the distance. Launch velocity is adequate. I've seen the behavior several times with Aerotech motors, some F44-4, but most with the F67-6c (Classic line). I no longer trust the Classics at all. Twice its caused a rocket to get stuck in a tree, and a close call (went into a dense treeline but by some miracle landed in a small clearing. Losing an $150 chute release would have really made me mad to say the least.
