As I've said for 10 years now... we need to request 50K windows. 35 K has been OK... but everything I've doing is 35K+. you never know if you're gonna get it unless you ask... and rag them about it.

Sorry I missed it. I didn't expect we would have a November launch after so many months of no launches or I would have prepped something. I've still got a bunch of K motors.

Good point James. I think it is just tradition that NCR holds the annual meeting in the beginning of January. Joe, what do you say to that?

One thing I've done in almost all my dual altimeter birds is to build a common power bus (usually two or more 9V batteries in parallel) and to tie the grounds from both altimeters together. I don't us...

I have 3 Hypertek motors and a number of grains. Two 54mm motors - the 435cc tank and the 850cc tank (pardon me if my memory fails on the specifics, but they are effectively I, J and J, K motors depen...

Unfortunately we do have quite a few members who either don't have email or our email list is outdated. That said, the forums are largely populated by a relatively small group of active members. This ...

Ok folks, I've been missing in action for some time with very limited computer access and so I haven't been participating much. That said, I am at least partially back in the world of the connected. S...

One point to add, keep the GPS transmitter as far as possible from the deployment electronics. Quite a few altimeters are sensitive to RF and have a tendency to fire their charges when the transmitter...

The only shielding issues you'd need to worry about are metallic objects and carbon fiber. Everything else we use is radio transparent.

I'll be in Berkeley CA on the 1st visiting mom. Sorry folks.

Having done it, I can say that making a custom nose cone is a labor intensive process and the results can be questionable without serious tools and tooling to make it happen. The main item is to make ...

I have 3 Hypertek motors that I'd be happy to sell. They're way cool to fly, but too fiddly for my current level of interest. The 3" L motor is especially interesting. I'd let all of it go (3 tanks, 6...

Was that the coolest thing you ever saw or what? I still think the method was a kludge, but they pulled it off and nailed a damn near perfect landing - within .9 miles of target after nearly 400 milli...

Wow... congratulations Adrian. Damn it all, I was just about to ask you to jump in and consult on a project with Mark Stumbaugh and I on a 100K N project. When are you moving?

I have 304L Stainless rail buttons for 1010 rail in quantity. Unfortunately I'm out of 1515 buttons and have no immediate prospects for making more. These buttons are aerospace grade and sure to add t...
