Awesome list and greatly appreciated. I much prefer “unofficial” records – less bs to deal with and still reasonable facsimilies of what’s been accomplished or claimed. Most of the altitudes reported by NCR members, at least on our home flying…   Read more»

Swivels that work and are capable of handling rockets over 3-5# are essentially unavailable in the hobby. The only source I know of is the sailing industry and they are extremely expensive as well as quite heavy. Given that several…   Read more»

just be sure to get a well rated one. I use the Rosco ones from Fruity Chutes.In my experience, they keep the main from wrapping up with the NC.I’ve also not used swivels. Sort of a matter of taste.

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.

make sure it is kevlar shock cords.I used (used nylon) on one rocket and it seperatedat apogee.

Talk to me baby – I have stainless steel railbuttons for both 1515 and 1010 rail with stainless steel screws. $10 a pair for 1010 and $20 a pair for 1515. Got you covered.

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

John, I personally NEVER use swivels – but that is a personal choice. For shock cord on a rocket like that, the 1/2″ tubular would work great – It is 7,200# test.Shameless plug- you can get that for $1.25/foot with…   Read more»

As a follow-up to my earlier posting, I’d like to try and gauge interest in “built” rockets. I basically don’t want to haul them to the meeting if there isn’t any interest.I have a couple KestreLs, a minimum diameter 4″…   Read more»

Nice thought Tim but the “Black Saturday” sale gets me every year. How can you say no to 30-40% markdowns on sweet all-glass kits? Well, I can’t. Hopefully I still have some to spend on JW’s high altitude hot sauce…   Read more»

8) I am going to save my ‘black friday’ money for the meeting. 8) Unless that wildman type guy has a 3.5 AMRAAM at a rock bottom price!!!!

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.

Backing up John on this, both of us flew very similar birds of about 32″ in length with J570s and dual deploy within 15 minutes of one another. Not a problem… both filament wound Hawk Mtn type tubing and couplers.Given…   Read more»

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.

John, I want to qualify my “you can’t push the tubing hard enough to make it fail” comment…. If you have a very tall rocket or a 2-stage that has a bad interstage coupler, all bets are off. That said,…   Read more»

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.

You cannot push either of them hard enough to make them fail (convolute or filament). Convolute is waaaaay easier to drill and sand. That was my story when I was a dealer and I’m sticking with it…

Filament wound tubing, like Hawk Mountain, Dynacom and Giant Leap is not as strong axially as convolute wound tubing like Performance Rocketry makes. That is not to say it isn’t strong enough, but that depends on the tubing, the motor,…   Read more»

Thank for posting Joe, very sad to hear. My condolences go to Gary’s family. He will be missed.

Amen and thanks to all those who have served. I think of this as thank a Vet day, week and year. It was the eleventh hour of the elventh day of the eleventh month when the Armistace was signed in…   Read more»
