There is an NCR roster, but it basically lives in Joe's little box of papers (Joe is in China) and a spreadsheet that Ken Plattner uses to track membership dues. By club vote a number of years ago, it...

I don't want to dispute you Conway - I just don't think the ARTS and it's GPS package are worth the money for the kind of rockets I build and fly. As Mike noted, out to at least 7 1/2 miles, this dog ...

Yes Conway, I agree there is far more to the ARTS than tracking. Range-wise it's certainly superior and all the flight computer capability. What I had with Jeff was a discussion (I think he'd consider...

Thanks - it might be a good idea to bring it along, but I think the club already has like a 2' x 3' whiteboard for the big launches. W

Sweet looking project Mike. I look forward to seeing it fly. Warren

I wonder if using shielded or twisted pair wiring would resolve some or all of the RF coupling issue? One problem I note with most altimeters is that except for the power supply negative terminal, the...

I would expect separation to be an absolute requirement after Mike's experience with his other transmitter rig although that was operating at significantly higher power than I expect the collars to tr...

I'm talking about bang-for-the-buck Conway. With an ARTS w/GPS, you've got over $1000 invested in the unit plus GPS module ($189+$850 - last prices I have for the ARTS and its GPS) and you still don't...

Thank you Mike. Very much appreciated. I've got to coordinate with Jeremiah as the development website is now running on a virtual machine on his laptop and he's got a large code dump we're almost rea...

Absolutely allowed. A number of folks fly Jim Amos' Missileworks WRC unit so feel free. Just make sure you coordinate with the LCO and the other folks who are flying R/C. W

Thanks Mike for putting this together. I just ordered 2 of the dog collars and will coordinate with you and Elvis on the collar # when I fly. This has the potential to be the best thing to happen to r...

Not only a mis-identified rocket part, but cheaper than a Big Red Bee plus receiver, FAR cheaper than an ARTS or an RDAS or any of the other made-for-the-purpose rocketry GPS units. Likely to have at ...

I typically thread the outside but not the inside. Meaning that I thread the airframe, but not the nosecone or the e-bay. This holds the screws in, but provides no clamping force. The screws stay in, ...

I ordered two of them Saturday after I got back from the launch. Too cool an idea. Warren

That sounds just about right to me Edward. I think I was seeing 48# shear per screw if torqued to the point they very slightly stretch. 42# if loose. W
