Warren is correct, by doing what you want to do with the closure then any motor using that closure is officially “modified” and is no longer a certified motor. Research launch only, NCR and TC have plenty of them. Those…   Read more»

This isn’t a problem Mike and I can easily accomodate you on this, however be aware that this makes the motor officially “uncertified” and while NCR usually doesn’t make an issue of these things other clubs may do so.Warren

Field trip!

It does look really interesting, pricey though. It is real close to Richard Specks office.

Kool idea – worth considering – maybe a bunch of us should plan a takeover one night and build something(s) outrageous.

Well sorta local. They dont have a full list of thier machines.

If you go with a little more space and it’s too sloppy, you can always tighten it up again by putting a thin coat of epoxy/microspheres on the outside of the airframe, and sanding it to get just the fit…   Read more»

…I’ve been getting more comfortable with the idea of using the sustainers’s motor as a coupler, if you can get one without a thrust ring…. .Hmmm, Adrian, that is an intriguing idea. I don’t want to say what I am…   Read more»

I have very thin mylar release – I believe it is .002. You’ll need a couple thousanths of slop in order to even fit the thing onto the airframe as the irregularities in the tubing will probably be that much…   Read more»

Mike, Like with the Tip to Tip glassing, I’d be happy to help out with this project. The key issue is having a mandrel to wrap around.WarrenI plan on using a piece of Performanc Rocketry (PR) airframe for the mandrel,…   Read more»

After building the electronics bay, I agree that is was complex. It is a very tight fit in a 2.2″ tube. But I like the challenge. I like to build rockets as light as possible and emphasize the engineering and…   Read more»

… my L1 project is progressing nicely so I shouldn’t wait too long. I finished the dual deployment bay and will soon be learning all about ejection charge sizing. ….Chad, That’s a fairly complex rocket for your L1. It’s a…   Read more»

Thanks for the thoughts. I’ve still got some time to figure out my chosen organization, but the work on my L1 project is progressing nicely so I shouldn’t wait too long. I finished the dual deployment bay and will soon…   Read more»

If you are stopping at L1, then I would suggest joining NAR, as there are more fields and events to fly from with the smaller rockets (and close by). Contesting in the regionals is fun, does not cost as much…   Read more»

Really all depends on what you’re looking to get out of your participation. If you’re into scale modeling and low power points competitions, then the NAR is probably the way to go. If you’d rather explore the edges of altitude…   Read more»

In v4.0 you have to put the new files into the “data” folder, then run the “engine database compiler” and then hit “reload engine data”.Not sure what version you have and if it is the same…

Don’t forget the step where you have to “Compile” the engine files before Rocksim can use them.W

Compile?
