Going Supersonic

I heard that a conical nose cone, as opposed to the ogive which you used, is better for supersonic flights. Also did you actually recover this rocket? Just curious.

what is the laws of a g motor do you have to do any thing with the state or can you just shoot it

You can just shoot it. You used to have to contact the FAA if your rocket weighed over a pound, but now they waived that regulation and you can just fly them (so long as your rocket weighs less than 3.3 pounds)

very good launch, very smooth launch, its a nice stable rocket. i wonder if the power of the motor has anything to do with it

A sonic boom can be heard as a sharp crack. Any one that has been in the Marine Corps and has pulled targets at the rifle range knows that the sharp crack that tells you to pull your target is the sonic boom of the tiny .233 round. A sonic boom can also be attained with a whip or even a towel if done properly.

lol, you actually thought the 2 pops like 5 seconds after takeoff was a sonic boom? the rocket was was too small for a sonice boom to be heard by the human ear.

Not true. A rocket of that diameter can and DOES make a sonic boom (or pop), it's just that the conditions are so rare for an observer on the ground to be able to hear one. However, I do know now that those two pops aren't the sonic boom, just the motor burning out.

s.o.a.b that thing can take off!

Very impressive! Did you get it back? My first 29mm min. dia. shredded. The next 2 I was able to keep together. Strong fin joints are a necessity. Although a shock wave was created. You probably did not here a sonic boom from the ground. Most likely it was the motor blowing chunks out the nozzle.

So next time, tie it and a remotely controlled launch assembly to a few helium balloons, wait until it's almost out of sight, then launch with the help of gravity so you can hear it better?
