If you will indulge me please-
I'm kicking around the idea of getting one rocket or another that will use a 29mm motor, but as I have only ever used single use Estes engines (18 & 24mm), a couple of questions come to mind. I've spent quite a bit of time looking around and think I know the answers, but for one reason or another, I'm just not quite sure if I understand for sure. You know?
I'll use the AeroTech RMS-29/40-120 as an example for asking purposes-
1. If I understand correctly, using this one casing I could reload it to 7 different thrust levels for use either in different rockets or for varying heights/weights?
2. These motors don't generally use a motor retention clip/spring like the Estes kits. They may use something like the Motor Retention System from Giant Leap Rocketry that performs both functions of keeping the motor from going up through the bodytube and from being shoved out the end at ejection. Does this sound about right?
3. If the rocket is small and light enough to fly on Estes E's and D's, there are adapters available to allow this. Right? Wrong?
4. Or..... I could get and build a rocket with a 38mm motor housing and an adapter to use a 29mm motor in it until I decide if I want to get active enough to get Level 1 certified. Of course, by that time I'll probably be ready to build another, larger roc..... Oh, sorry. Started rambling.
Sorry if these are low-brow questions; I'm kind of at that stage where "I think I would like to get more into this", but don't have anyone around in person that would have made watching and learning the way to go.
Thanks all, Have a good one,
Greg
