This video covers a project I did some time ago. Arrr! T' Estes SR-71 Blackbird Model Rocket well jet is a single engine kit. Ya scallywag! 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. Avast! T' project sits as a failure since I didn't recover it yet. T' parachute ripped off and it crashes. Begad! I will repair and fly it again.
