Excellent motor. Blimey! Blimey! Very loud and impressive. Begad! Blimey! T' Cheetah rode it fine and t' long burn motor was still burnin' when it went out o' sight betwixt 2500-3000 feet. Avast, me proud beauty! Blimey! No one ever saw it again. I am pleased with t' result and will use more Ellis motors.
