kpknd Posted March 19, 2013 Posted March 19, 2013 Do you use your motors for models? I'm working on a project to use an 8oz. motor.
JFeve81 Posted March 20, 2013 Posted March 20, 2013 If you mean like the toy "Estes brand" type model rockets then yes. In my 8th grade science class we made sugar rocket motors. Blew many a rocket to shreds with them. Haven't tried making any BP motors for them though. It's something I've been wanting to do but haven't got around to yet.
nater Posted March 20, 2013 Posted March 20, 2013 I built a small rocket that will fly on 1/2" motors. I wanted to use some of my larger motors on rockets, but the local HPR club only allows certified, commercial motors.
Oinikis Posted March 20, 2013 Posted March 20, 2013 i haven't seen any comercial motors. now i'm working on my tooling, to make motors.

When I used mine at the rocket club it was okay but they REEEEEALLY had kittens if I put a fuse in it.

There are a couple local guys who make their own, but they just have fly them at larger events than the local days. Next month, they have a full scale Patriot launching on an EX "P".

AirCowPeacock Posted March 22, 2013 Posted March 22, 2013 Whats wrong with visco anyways? Just use a good amount. At my local HPR club, your still only 50 feet away from rockets, and people are ramming 3 lb rockets at the viewing area, 50 feet away!
nater Posted March 22, 2013 Posted March 22, 2013 (edited) Our club is a chapter of NAR, part of their safety code requires electric ignition and forbids anything but commercial motors. Tripoli clubs allow for "research" motors and independent clubs can do what they want. Those rules are part of the reason hobby rocketry even exists in the US. I am sure Estes and Quest did some serious lobbying though in order to keep the motors classed as toys and not fireworks. Using visco would probably push them to the side of regulated pyro. What gets me are the rocket guys that are so anti pyro. Some of them are pretty snobby about it and hate the experimental APCP motors too. Edited March 22, 2013 by nater
dagabu Posted April 8, 2013 Posted April 8, 2013 Not only that but when the ATF decided that APCP was explosive and hobbyists could no longer have garage magazines, the clubs decided this was a great time to limit if not eliminate all scratch build motors, at least my club did. thats why I got into pyro in the first place, just to make motors. 1
