Several days ago, I started work on one of my torpedo shaped rockets, but my next completed build will probably be something more conservative.
I've been concentrating on rockets powered by 18mm motors. Cheap to build, cheap to launch, and plenty powerful for the launch site I'm using.
I recently bought a Jolly Logic 2 altimeter. I tried to install it in a BT-50 rocket, that had a baffle, and there wasn't room for both the altimeter and the chute.
At this point, I'm unsure how long a body I need to get the room I need, in a rocket without a baffle. Could be fairly short, but I'm leaning toward longer bodies for the dynamic stability you get.
As you can see, the stability is pretty high, on this rocket. I could, theoretically go with smaller fins, but they are already pretty small. I'm afraid to go smaller.
Elliptical fins might be a good choice here, but clipped deltas are pretty efficient and easy to make.
I already have a similar rocket with swept clipped delta fins. After a few launches, I'll decide if I can go shorter.
