Rocket Alpha3DP

Alpha 3DP Model Rocket for 18x70mm Estes Motors (A8-3, B6-4, etc)Inspired by the Estes Alpha III rocket, this 3d printed rocket is similar in size, but a little longer tube to ensure stability.The body tube has secondary 50mm inner tube that is not attached to the outer tube. It absorbs the heat from the recovery charge, making this rocket very reusable! I have more than 20 launches so far! Additional material required: 12" parachute (Estes 302264 or equivalent) Long rubber band or shock cor
