In practice, you’ll find that it’s pretty difficult to get two barometric altimeters to fire at the same time. Aside from sensor tolerances, altimeters like the RRC2 family just don’t have the resolution or precision to fire at the same…   Read more»

I was thinking about it yesterday. I Have a 3″ Rocket(not much room)In our redundent alt. ejection systems Ken had 2 Powder cups, Mike has 2 Powder cups, I have 2 Powder cups. If your testing ejection charges and getting…   Read more»

Any body have any experiance testing altimeters? The instructions says use a tube on the baro senser and draw a vacume. Joe told me some in the club, have some neet ways of testing them. ??? Food saver? Scott eI…   Read more»

Very nice, Scott. I know your altimeter will work and you’ll nail L2! Before the thread police come in, we better get back on topic.

YesThe hard part is getting the wire from point “A” to point “B” and being outside makes it a little harder.BUT BRUCE!!!! 220 in a garage ISNT AN UPGRADE!!!!ITS SURVIVAL!!!!! Seriously though, all that glassing I did, in the last…   Read more»

We’re going to sell this house in the next few years, and I don’t want to upgrade anything at this point. I can live with hurrying in Feb & Mar to get things done. Panel’s outside. Don’t wanna go there….   Read more»

I rewired an entire house, plus some other stuff.Wheres your panel?Some times the panels right in the garage.Getting 220 is easy then!Scotte

Sweet. Warm enough to cure epoxy. I have an electric heater, but not THAT strong! 220? Wow. That’d do it. 8)

BruceYou should get one of those 20,000 btu heaters(220 electric) like I have.Keeps the old 2car at about 60-65 degrees.scotte

I do believe the altimeter did its job the last time. Both parachutes were burned(the main moastly). But they didnt eject. I think the maximus amount of powder I put in, trully blew the sides of the rocket out(not enough…   Read more»

Just would like to know that they are doing what they are supose to do up close. Not 5000 feet away like last time I understand. Though never had that happen (the altimeter being bad), just something I did, or…   Read more»

The cheapest gauge Aircraft Spruce has Is $110.00 (reads in inches)For that I could buy a small digital altimeter, which is kinda what I had in mind any way.Scott, just buy a MWC mini altimeter. You’re putting yourself WAY into…   Read more»

Yeah… wish I had a heated garage. This time wouldn’t be wasted. I have two rockets to build for next year, and they’re sitting in pieces, just waiting, out in that cold garage. We all understand the need to make…   Read more»

I might try that.Im not trying to get to ridiculous with it but, I also might try to find an aircraft style (without the price, something cheap) manifold pressure gauge to hook up. They read in possitive pressure instead unlike…   Read more»

Scott,The simplest way of testing some baro altimeters is to take a straw and place it right on top of the pressure sensor chip and take a in a big breath. You can at least get an altitude reading.One thing…   Read more»

I don’t know that I’d use a food saver, but I’ve never tested one like that. BTW – you have a PM.Ken.

No, not on this one.I will start getting into glassing or buying “pre-glassed” air frame, fiberglass or some other stronger frame this year.I will start with smaller 3″ or 4″

Mike, any chance you’re going to glass the tubing?
