A 1/4″ gap would be something I would try to resolve with epoxy or sandable filler. Foam would be great in between the airframe and the motor mount tube as a filler. If you have a visible gap in the…   Read more»

If you’re going to do the syringe thing, don’t draw it back into the syringe, get the syringe all set, remove the plunger and then fill the barrel directly, reinsert the plunger and go. You really don’t have the time…   Read more»

I’ve gotten much better at judging foam volumes… small amount take a lot longer to cure as the stuff is exothermic like epoxy. More in one place results in greater heat, greater bubbling, greater volume. Oh yeah, newspaper on the…   Read more»

There are a variety of formulations of 2 part urethane foams out there. PML happens to be a pretty agressive formula with approximately 25:1 expansion ratio for the straight up 50:50 mix. I ALWAYS foam any thru the wall fin…   Read more»

This is a Linux/Apache/PHP site and is largely built on PHPNuke for the basic content management… The forum module is called PHPbb. If you’ve any experience working with PHP code, definitely give me a holler, I need some help.Warren

I’ll take a look at that Conway, but it’s buried deep in the commercial code that runs the forums. I know it’s possible, but finding out where in the code it is could take some time.Warren

Now, now boys… I would like folks to stick to forum thread topics and to create new threads if the topic substantively changes… but we don’t have to be topic nazi’s here… Best if our moderators (and we could use…   Read more»

I could readily set up a projects area for folks…sort of mini-web pages for projects, though I can’t promise it would be ready before Septemberish given my travel schedule.Warren

I’ve been fiddling around with a hybrid device by Radiotronix. The Wi.232FHSS-250 is 250mW, up to 7 miles line of site, 2400-152K baud RS232 wire replacement. The modules are $40-$60 ea. depending on the packaging version. They use the 900-916…   Read more»

I’m talking about more professional grade stuff. The camera’s I’ve seen run about $100 or a little bit more.Warren

Lipstick cameras John? I’ve seen ’em, have a source for them too but don’t have it handy. I’ll try to track it down and post it later today or this week. They’re even smaller than you’re talking about. Cylinder 5/8″…   Read more»

Actually, I hadn’t thought of putting one in there Doug… I’m definitely open to your suggestions because I don’t know anything about flying cameras…Warren

There will likely be some considerable differences… and drag racing N motors will be expensive. My bird will be 9′ of airframe and depending on whether I use the nose that came with it or a new nose will be…   Read more»

I have to say, this Competitor 5 kit from Performance Rocketry that both of us bought is a great kit. I’m bashing the hell out of it, adding a tail cone, extending the motor mount to be large enough for…   Read more»

I’ve built 2 birds with the Giant Leap 1/8″ G10 honeycomb for fins and bulkhead material. I love the stuff. Expensive, but pretty easy to work and LIGHT!!!!. The biggest issue is edging it effectively.Warren Musselman

I’m interested in APRS, but haven’t had a ham ticket since 1976 when my general lapsed and I sold all my radios (electric guitars and girls had a serious impact on my radio involvement at the time). Now I’m fooling…   Read more»

In High Power Rocketry I believe, I saw an article about radio controlled rocket recovery by chute steering… I’ll dig those out today and track down the article for you.Warren

The current version of the flight computer product I’m playing with developing talks via bluetooth to my mobile phone. One of the options will be text messaging GPS data, altitude, temperature and acceleration via cellular text messages… unfortunately, our launch…   Read more»

You’re dreamin’…. while SOME folks are able to get coverage (Joe Hinton is one) WHEN at the top of the hill, I know of no one with coverage reliable enough to receive calls. Occasionally, you can make a call from…   Read more»

Well, I think you’ll find your issue is primarily the rod you launched off of. I fly my Io off a 1/4″ rod all the time and while sometimes a little rod whip occurs, it’s not a big deal. The…   Read more»
