i like your videos. I used the same propelent as in your video, but I put it in tin foil and glue it to a stick and it flies only over the telephone line. will it be better if I nake your engine casing?
the high impulse motor has a couple changes. It burned a single central core as opposed to the long burn motor's "moonburner" grain which has an offset core and burns slightly slower. Also the high impulse motor's propellant grain was larger and made more thrust but with a shorter burn time and had an ever so slightly smaller nozzle. The pressures were much higher with the high impulse motor. The long burn motors nozzle was slightly larger and the pressures were lower but burned for much longer
i guess it was just an error cause I can hear it now too. Now if I could only get the stupid neighbors dog to shut up. Watch the person in the far far background suddenly stop in their tracks when it lifted off!

Nice motor. Now how do you make the r-candy high impulse and long buring? More sugar or..?
