My suggestion for gluing down the flap was just for a few test motors. I can't imagine doing it for a thousand motors!
I have some cotton swabs on sticks that I use and I "believe" at least one SEMROC kit included one for gluing. If it is successful in preventing a burn-through, at least it is a data point for the tube manufacturer to find a correction (and the old casings becoming collector items...). Carl, any approximation of the burn-through rate on your test motors? Was it prevalent past a certain delay time? Is a three second delay good and five or more a problem? Oh, and Bruce is right. B14's! Chas

Carl, thank you so much for working on this. Emma and I really need 10 mm booster motors to practice staging, so the difficulty with the delays would not cause us a problem. Thanks again for spending so much time on this,
Steve and Emma |

10 mm Motors
WOW!
Just caught this thread today, I wish you every success in fixing the burn through problem. I would echo Mr. Russell's suggestion re sealing the inner tube with CA, many of us already use thin viscocity CA to prevent fraying of our body tubes, so it should work well due to its wicking ability with the motor case. When you get this problem licked, please contact Taras Tataryn to check on Canadian importation as there are several of us CAR members that have been playing with FAI competition and to have motors equivalent (or better) than the Europeans would be a real boon. Also B14's .....Yes! Garth Illerbrun SAM 20 CAR S04 |
