mylar is non-porous (unless you buy special perf'd mylar) so you don't use anything in between the mylar and the tape. You ONLY use non-perfed mylar on the finish layer. All underlying layers should b...

Honeywell sells ring-laser gyros and IMU's based on them for not a huge amount of money - about $11,000.00 for a flight-worthy unit rated sufficient for rocketry. Warren

My 4" carbon bird was pretty close to the ideal ratio of fabric to resin and came out about double the weight of the phenolic tube. There were 4 wraps of 5.6 oz carbon and a single layer of 3 oz glass...

The biggest problem with solid-state gyros (the only kind we can afford as hobbyists) is that they are rate-gyros, not absolute position sensing gyros. They'll tell you the rate of rotation, but drift...

Well I want dibs on a production unit Adrian. Any possibility of getting one within the week? I have some F and G motors that go out of cert on 12/31 and I need to make sure I take those altitude reco...

Do one layer at a time if you're v-bagging and make sure you squeegee all the excess out of the fabric before and after it's layed up. Then wrap your peel-ply tight so that there are no bubbles, next ...

I think it's time to end this thread - 8 pages that ramble over at least 5 or 6 topics. Consider it locked. Scott, time to start a specific thread for each specific topic, the rest of you, stop changi...

Rocketryplanet gets a bit chatty for me. Much prefer it here. Warren

A little automotive paint store right on the south end of Main Street in Longmont. Can't remember the name of it, but it's in what used to be a house, South of 1st and north of Ken Pratt on the west s...

I personally use the low-end PPG paint. The clear-coat is a two part paint and they have a primer that is two part, but the paint itself is just thinned with reducer and sprayed. Typically it is in th...

😳 blush 😳 Wait until the annual meeting - we'll be rolling out some new stuff. W

100K in a day has already been done - by an NCR team. A single 38mm rocket, a group of NCR folks, and free 38mm motors from Cesaroni made it happen... There is a photo gallery about it in the Photo Al...
