17. ### Flight Computers: Accelerometers vs Barometric Sensors

I've got some experience with the basic eggtimer flight computer, which I understand is a barometric sensor based flight computer. I'm now working towards my L3 and needing to invest in a 2nd flight computer to meet the redundancy requirements. I've heard that for an L3-cert level flight...
