So while waiting for parts to come in I am contemplating another build. It's the Nike-Nike Smoke and I am thinking of building it as a 1/10th scale single stage. That makes it a BT-60 tube, overall length is 40.88 and it will fly on a Estes 29mm F engine.
I am trying to decide about using a 8" long engine tube versus a 17" long engine tube.
I was going to load my open rocket files but it doesn't seem to like them... I did do both and both mocked up fine. The 8" tube has a caliber of 1.6 and the 17" tube has a caliber of 1.5
So pluses of the 8" tube. I have all the parts on hand. The lower fins can be thru the wall. Minuses are that the upper fins won't be thru the wall and the larger area between the engine and the nose cone for ejections.
Pluses of the 17" tube. Both sets of fins can be thru the wall construction. The area inside the tube will be reduced. Minuses are that I would have to order the tube.
I'd love to read your thoughts
