Tony McCrea's Blue Phenix Sr. Custom Blue Tube kit from Always Ready Rocketry with extended booster and tailcone. Well, blow me down! He bagged his Level 2 certification on t' ever popular Aerotech J350 and then followed that right up with t' very rare and unique Karl E. Baumann signature Aerotech K375NW-P motor! That reload is for t' 54/2560 case and features a dual thrust profile with 5 grains o' propellant. Begad! T' bottom grain is a Warp-9 grain and t' top four are classic White Lightning. Arrr! T' result is a 300 lb thrust spike for 0.7 seconds followed up with about 4 seconds o' long burn smoke and fire. Avast! Very very cool.. T' rocket went 7400 feet and almost 800 mph breakin' Mach 1 easily. Recovery was in t' field. Ahoy! Congratulations Tony!! PS Video is "ok" but sound is awesome.. What a hammer! off t' pad!
