Doug,I am interested in using your services for launch of my 2-stage at Octoberfest. What would be the pre-paid cost of the pictures?John Nelson

Thanks Edward. I will look you up for those o-rings. I have two new rockets, one using an M motor and the other is a two stage 54 mm motors on it so I do not want to jeopardize their… Read more»

Thanks for the info. guys. Can you purchase just o-ring kits from the motor mfg’s? If the grains have oxidation going on what will it look like?

Tue, 09 Jul 2019 06:19:35 -0600

I have some Contrail motors and one Hybrid ready rocket. I plan to fly them as soon as the chance arises. I do have my own tank though.

Thanks Mike, I am going with Kevlar from 3 dogs and Warren I am interested in your railbuttons. Still in planning stages but I will take a pair of 1010’s and a pair of 1515’s. Thanks.

Thanks. How about rail buttons? Railbuttons.com is belly up.

Tue, 09 Jul 2019 06:16:44 -0600

This is not a minimum diameter project Warren. For the materials Performance Rocketry is about $100 more with some “waste” due to the tubing available only in 48″ lengths. Hawk Mtn. has more variety of lengths.

Tue, 09 Jul 2019 06:16:44 -0600

John, I am looking at a rocket about 13 feet with a joint in booster for parachute deployment and the sustainer a dual deploy. Sims about 22,000 feet. I would use G-10 couplings and shear pins.

Tue, 09 Jul 2019 06:16:44 -0600

Thanks Warren and John for the reply. I think most of us take for granted how valuable these forums are to this hobby. Appreciate it and I am sure I will have more questions building this project.

Very interesting website! There you go John, no fins- less drag= more altitude! Thanks for the info Ken. It amazes me how high tech and multi-facetted you can get with this hobby.

Sparky2 replied to the topic "Rocket Design" -

Tue, 09 Jul 2019 06:02:15 -0600

Thanks John, I didn’t even think about the steerable motor. That has got to take some serious computer and motor mount engineering. That type of steerability is not legal in HPR right?

Mike , did the State come out and inspect your magazine? Is it in a residence and if so did they accept the NFPA 1122 and 1127 rules for the magazine location in a residence?

James- I have 54mm Contrail Motors. This rocket can use either the 28inch or 36inch casing and a J reload. I have the NOX tank and solenoids. I planned on a 24volt igniter with two 50 grain pyorodex pellets.
