First Flight o' t' Sooper Neon, Level 2 Cert Attempt. Great boost, much lower than expected based on sim prediction. Good drogue at apogee. Begad! Main charge fired at 500 ft, main chute did nay deploy from BT. Ahoy! Mud landin' under drogue, no damage.  Postflight inspection revealed t' chute bundle tightly wedged in t' body tube, I will need t' re-think me packin' methods for this rocket.
