After a getting back into rocketry, I got bitten by the altitude bug again, so I decided to revisit my 29mm high altitude two stage rocket. I think that I have most of the design for the new one figured out in broad terms, so I'm going to start working on building a testbed rocket out of more conventional materials to test out the electronics and deployment sequence. This means that I have to settle on the electronics now.
If all goes well, I might put a 38mm stage under the two 29mm stages, which would in theory get me to altitudes well in excess of 30,000 feet. Because of the GPS tracker requirements for setting Tripoli records, that pretty much narrows my tracker down to either the Featherweight tracker, or the Telemetrum. If I use the Featherweight tracker, I can quite easily pair it with a Raven 4, due to their shared footprint. The Telemetrum could be paired with the new Altus Metrum Easytimer, which would give me tilt inhibition of the staging, which feels simpler than relying on speed and altitude lockouts on the Raven. Ultimately, I care most about reliability. Assuming a competent installation and setup, which avionics package do you think would more reliably control flight events and track multiple stages?
