No rambling at all Mike. That is a great idea. That’s the kind of thing I like to see posted. Ideas are the basis for everything and finding rocketry components mis-labeled as they are all over the spectrum of products,…   Read more»

Put the battery in with the wrong polarity and I guarantee you that will happen with an RRC series altimeter. Ask Jon Skuba sometime…Warren

That was old video. Sadly, the “MISSILE WORKS” decals were in clear sight.IIRC The guys had the wires backwards on the batteries. When they didn’t hear beeps, they didn’t stop and check things out. After a while, things overloaded and…   Read more»

I lost a big Endeavor couple years back–the cone is still out there on the prairie. She also come in ballistic at terminal velociity or mear enuf..the quantum tubing shredded into tiny shards, none more than a couple inches, most…   Read more»

No need to panic – I tend to be at the front of the panic curve so wait for me to go ballistic. I haven’t flown even once this year so I guarantee you I’ll fly off the handle first.Warren

agreedI am sorry.i sure did not mean it to sound like i wantedto replace the North Site.just trying to help in my panic mode.

If NCR needs another HP launch site, much better that it be further south rather than further north. The North Site is onerous for many club members to get to as it is. Unfortunately, a site where there are no…   Read more»

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 the same time with the Parrot?I’m sure it does;…   Read more»

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 same chamber…   Read more»

Adrian,Let me know what you find about regarding the chamber test. I’ve built a couple of altimeters that I just messed around with. I would like to find a better and more accurate way of testing.What I have done is…   Read more»

IIRC he also needs a unit to chamber test, etc. Keep us posted-J

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.

Thanks, John.I sent Tom an email asking about what I would need to do to get the Parrot certified for official Tripoli records. In the meantime, I’ll have fun seeing how high I can go unofficially. I’m looking forward to…   Read more»

Hmm.. I couldn’t find anything about altimeters anywhere on the site. But I’ll contact one of their people to see what’s required.Adrian, the guy in the know is Tom Rouse:Tripoli Contest and Records CommitteeTom Rouse7170 Wooded Lake DrSan Jose Ca….   Read more»

Only if you get it on the approved list from Tripoli and NAR. NAR doesn’t actually certify ANY altimeter for altitude record contests. Tripoli has a fairly short list that leaves a number of commercial altimeters off due to “issues”….   Read more»

I use that PL Polyurethane construction adhesive all the time in my business. Two recommendations: score the surface you intend to ahere to and make sure it’s clean, and do a strength test after it’s cured. I use it to…   Read more»
