This is a Polecat Aerospace kit featurin' fiberglass nose cone and fiberglass wrapped body tube.  54mm motor tube can be adapted with Aeropack fixture t' 38mm. Avast! 54mm Aeropack motor retainer is used. No nose weight was added or needed per kit instructions. Avast, me proud beauty! I created an altimeter bay in t' nose cone and planned t' use t' Cable Cutter for main deploy but have heard thar are reliability problems. Begad!  T' Jolly Logic Chute Release is me preferred solution now for t' main deploy.
