A naked prototype for a modular minimum diameter altitude bird with multiple booster sections for specific motor cases. This particular configuration was for the AMW 54/2550 motor case although that isn't the motor that was flown.
Dual deploy - no apogee chute or streamer, just airframe separation with a Kevlar shock cord.
Main chute is 36" nylon chute, probably a LOC or PML chute leftover from a kit.
