My guess is that we could leave a note in their mailbox for an invite. If you do, make sure it is "by the mailbox", not "in". I believe that's a felony if you're not the postman or the owner of the b...

I would caution against the "Great Stuff" spray can foam. Most (but not all) of the spray can varieties rely on exposure to air to cure, unlike the epoxy-based 2part foams that (justifiably) cost a bi...

No need to stress out about the cert, or rush it. You can do plenty of playing around with dual-deploy at L1 power levels. I did motor eject for my L1 and the next 2 flights, then electronics ever s...

FYI, CATO is not an acronym for anything. There's a nut over on TRF who just goes ballistic on anyone trying to use it as such. It's just a shortened version of catastrophic failure (which could be ...

Edward's got a lot more experience than me on this, but my experience (at least in Colorado's excessively dry climate) is the motors will be fine. I've flown multiple Aerotech blue thunder motors (29...

All I know is Chris's N5800 attempt shredded. No details yet from him. I was really hoping he'd be successful and show those all metal rocket guys some tricks.-Ken

In my tests with Mike Konshak on the DC20, we found the older Missileworks RRC2 had an issue since it had no ground plane. The PF MAWD in mine seemed to be OK. Discussions with Adrian suggest the Ra...

Internal changes will not affect CP, but will obviously change the CG and therefore the CG/CP relationship for stability.-Ken

Personally, I'd highly recommend the CTI motors for any cluster, staging, air-start application. I've had great reliability results with them with no fancy igniter prep. The Smokey Sam would provide...

Definitely bring along a notepad to keep track of the ideas on your first outing. I know when we first got our popup, we made a huge list of 1) things we should have brought along, 2) things we didn'...

Sorry, way off topic, but honestly haven't heard anything of KM since the outhouse. So true about the ego. I've never come across anyone even remotely like that in our area. We definitely seem low-...

Agreed. No easy solution. I've had a number of my son's LPR birds returned to the LCO table when we had given up hope of finding them, so I'm thankful to those who do so. I've only found a few, usu...

Look under the duct and flue brushes.
