By the way Adrian, put me down for one of those altimeters when you've got one that will do at least Apogee deployment. Without electronic deployment, you really can't optimize for altitude. Grr. Bil...

I'd be interested in seeing that if you could bring it to the next launch. I could drive they keying with the spare switched output on the Parrot, but then it wouldn't be a factory-standard altimeter....

As to the 90 percent point, (at least with F and above) I would have to opine that would be sometime during descent after the recovery device has deployed and someone has seen it recently or they have...

What's flight weight? How much do you expect to charge for them? The last time I weighed one with an accurate scale, it was 7.6 grams, but that was my first prototype. Since then, I've added some ...

Oddly enough, I have not flown an A, B, C, or D motor in perhaps 15 years. On top of that, I have never once flown an E. Given my geographical constraints, mayhaps I will revisit that whole paradigm (...

A lot of Orion is getting designed right here in some buildings at Wadsworth and Hampden, and there is at least one NCR member working on it. The rest is spread out between Houston, Arizona, Clevelan...

Let me say up front, before I'm tempted to talk any trash, that I really respect what you guys have done, both in the area of records (John's G record bird is (was? :() a thing of beauty) and more imp...

I suppose I should be asking Tom Rouse this, but do you think that the ejection charge reduction/elimination would disqualify a Tripoli attempt? When I go for the F record I want to make sure I tag a...

I have some questions about record rules: Is a "boosted dart" an unpowered payload section that recovers separately from the booster? I checked out the Tripoli rules and boosted darts aren't disallow...

My altitude watch changes *dramatically* with the change in baro pressure. It constantly needs re-calibration. Curious if you have tried tossing in other brands of altimeters into the same chamber at ...

What I've been using so far is a shop vac hooked up to an airtight container. The Shop Vac pulls the equivalent of 3000 feet of altitude. I have a well-calibrated altitude watch that I put in the s...

What can we do to cross paths so I can either borrow it or get explicit measurements so I can make a size mockup to fit it in place? Sometime today I'll post a dimensioned drawing. I also have a a co...

A week ago, he asked for me to give him all the data I could about the altimeter, and I replied with a bunch of information, data and graphs. I haven't heard back since, so I'll ping him again today...

During a shake-down flight this morning for my new 29mm F record attempt rocket, I accidentally exceeded the club record for E, using a 24mm E15-7. The shock cord broke and the Parrot altimeter I'm u...
