This is a two stage rocket that has some interesting features such as a side chute ejection and micro switch activation of main stage motor. This is estes powered d12-0 first stage and e9-4 main stage. The chute did not deploy for the booster stage (my fault, I did not put wadding in for baffle pistons). The main stage worked as designed but had a hard spin once the motor kicked on. I am thinking this is because of the camera not being flush mounted. The flight was satisfactory and the recovery of the mainstage was complete.
