A couple of tips: Paper towels make pretty good breather material.Sealing vacuum bags with bag sealer tape is sometimes necessary, but almost always a pain. Whenever I can make it fit, I just use a la...

My mistake; I thought the question was about the Beeline GPS. Agreed about the version with the 900 MHz module.

The main reason to get the beeline GPS is that it's smaller, easily fitting into a 38mm coupler. You would also need a HAM license to operate it. The Telemetrum combines the GPS tracker with a basic...

Maybe a better alternative is to roll your own. Dry carbon fiber is really pretty cheap, and there's lots of information out there on how to do it. 38mm mandrels are available from McMasater-Carr, t...

Does someone have his email address or know his log-in name? Thanks. -Adrian

And congrats to John Wilke whose I216 flight was officially recognized on the Tripoli record site, too.

After I rebuilt my computers and lost RS 8 in the process, and after pointing out bugs that didn't get fixed in RS 9, I gave up and I only use Open Rocket and RASAero now.

So the graph that it plots for you isn't accurate? I use this feature all the tim but I haven't built anything yet that I've flown enough to really test it's accuracy. There have been many times wher...

There's a feature in the simulation area where you can run the mass optimizer. The problem is that it is horrible at finding the optimal mass. I have found it's better just to adjust your nose weigh...

Check this out. I was kind of amazed that the public opinion was as low as it actually was during the Apollo program. It was never more than 50% except right after the Apollo 11 moon landing, when i...

I decided to abandon the KISS philosophy and go with what I was excited to build, attempt and fly.... and am nevertheless still working on the L3 cert. 2 attempts, a complete loss and a second purcha...

First, let me preface by emphasizing that the only way to really know is with a ground test. Go through a simulated flight and look at the real-time data (since the baro data isn't real in the simula...

The types I have used are teflon-coated fiberglass, and coated polyester. The FG is nice and flat and smooth, but it doesn't conform to shapes with compound curves much at all, so I'd only use that f...

Upon looking more closely, I discovered that the $8 per piece cost for the 3-axis gyro only applies when buying 100 reels of 5000 pieces, not 100 pieces. And at Sparkfun prices I think that would jac...

In an ideal world, what I'm looking for is sort of an enhanced Telemetrum with 3-axis accel, rate gyro, mag sensor, temp and humidity sensors and a 100K capable baro sensor - not to mention extended r...
