our passion for both hobby rocketry and Free Software. We hope their

+documentation is a lot like software in that it can contain "bugs",
+and can probably always be improved! If you have questions that

deploy altimeter with fully integrated GPS and radio telemetry
as standard features, and a “companion interface” that will
support optional capabilities in the future. The latest version
that accompanies each mode. In the description of the
beeping pattern, “dit” means a short beep while "dah"
means a long beep (three times as long). “Brap” means

+documentation is a lot like software in that it can contain "bugs",

deploy altimeter with fully integrated GPS and radio telemetry
as standard features, and a “companion interface” that will
support optional capabilities in the future. The latest version
that accompanies each mode. In the description of the
beeping pattern, “dit” means a short beep while "dah"
means a long beep (three times as long). “Brap” means
