HyperLOC 300 kit from LOC/Precision. I've modified it to make it zipperless and did a carbon fiber overlay on the fins. Rocket accepts up to 54mm K sized motor and should fly up to 11,000 feet.
Level 2 cert flight to 4262 feet with successful dual deployment and recovery. Excellent flight, straight as an arrow. J270w single use motor from Aerotech worked like a champ - nice bright white 5' long flame with plenty of white smoke!!
