This video covers a project I did some time ago. T' Estes SR-71 Blackbird Model Rocket well jet is a single engine kit. I converted it t' launch on 2 engines. I made a way for them t' both fire and eject t' parachute out o' t' aft o' t' rocket/jet. Ahoy! T' project sits as a failure since I didn't recover it yet. T' parachute ripped off and it crashes. Ya scallywag! I will repair and fly it again.
