After 25+ years out of model rocketry, I'm jumping back in with both feet and building a North Coast Rocketry "Laser Hawk" that I bought from Apogee. I was fairly active in LPR in my teens and even competed in some NAR competitions. When I got out as a young adult re-loads were just coming onto the scene and I have no experience with them.
The Laser Hawk is designed for a 29mm motor (F-G) single-use motors, but there is no retainer ring or clip. I'm considering buying a re-load casing. I've looked at some of the info regarding Aerotech re-loadable motors on the Apogee website, and I understand that the aft closer acts as the stop, but what retains the motor in the engine tube at ejection? And... they're listed as 29/60, 29/100, 29/120, and 29/40-120, etc. I assume the second set of numbers is the length of the grain(s) that the case will hold. So does that mean if I bought the 29/40-120 I have more re-load options than just the 29/60 or 29/100? Is my limiting factor the length of my motor tube in the rocket? I'm so confused :confused2:. Help me to understand, please.
