  1. Tests Great!

    Yet to fly onboard ... but static vacuum tests work perfectly! Looking forward to the data!

  2. Amazing altimeter.

    This is a great little altimeter. It almost replaces the $100 counterpart that's out on the market. Notify me when you get more in stock and I'll pick up a couple more. I know they're going to sell out fast.
