This video on the right explains the process. I’ll be adding a few more details to this page in the future. For now, here is a list of engines that will work well for this project:
Estes A8-3 – This is engine I’d recommend – a lot of fun without losing the rocket
Estes B6-4 – a bit more powerful
Estes C6-5 – This one will push a small rocket out of sight – good luck finding it!
