right now my current project is a 4 inch wide black brant 2 that is 6 feet 4 inches tall. i built a poor one before, but this this one is gonna be bitchen. for 88 dollars i had 2 tubes cut, one 22 inches long, one 20 inches long, they are hawk mountain fiberglass tubes, very high quality. the nose cone is a scotglas 3.9 inch black brant 2 nose cone, it was 55 dollars. i put a 3 inch motor mount in it and have constructed 2 other motor mounts that slide into the 3 inch tube, one is a 38mm tube, the other is 3 29mm tubes. i flew my other BB2 on one G, 3F's and 3D's. it did 1850 feet, and it jumped off of the pad broke on the landing, and zippered, i didnt like the design any how, so im doing a new one useing the old nose cone. 3 g 64s should do nicely in my opinion. when i turn 18 in november, i plan to certify on an AT 38mm I motor, with accelerometer ejection in dual deployment.
the tail cone i used i made myself and am quite impressed with, in one of the recent rocket mags, there is and article on how to make tail cones. what you do is work the formulas so you have a paper pattern and when you roll it it makes a tail cone, i fiberglassed the outside, and had an excellent tail cone.
the parachute is a PML 54 inch chute with a 4-5 inch spill hole
if you are interested, i can get you dimentions on the actuall black brant 2 and the dimentions of mine, with drawings of the construction of the motor mount, on my old BB2, i did not use roc sim or any of that, yes stupidly i admit, but with the length being as long as it was i though for sure it would be stable, it was perfectly stable on both of its flights, so be sure to make sure that it is long enough for its diameter. i know i guess ive done a bit of describeing what ive done, but it was a very beautiful rocket
if i might say so and turned many heads. i actually got a "heads up" 10 second count down. . also the way i did it, i could level
one and level 2 if i wanted to. so its quite diverse. with fiber glass
tubes, the strength is higher so worry of shred is less. if i was insane i could fly it on a 75mm L motor, but i dont think ill try that.
good luck and email me if you have any questions, also i can show you how to make your own cenering rings too, me and my dad came up with a brilliant wayof doing it
