I am an old lapsed rocketeer who now has grandkids interested and I have some old ProDyne motors I would like to build around. The Cyclone motor has a 1 inch motor diameter and varies in length and probably is in the low E category The Hurricane motor is 1.125 inch in diameter and also has various lengths and might be in a high E or Low F range. I am not looking for ultimate altitude just want to see how they perform. Being that they are old engines I didn't want to invest a lot of time or money in case they don't work.
