In the planning phase of my first electronic deployment rocket. I'm building a 3" Punisher with HED. Been doing a lot of research on altimeters, switches, batteries, and bay design/layout. I've been posting and commenting but decided to create a separate thread to consolidate all my thoughts. I'm guessing that if I am going thru this now that someone else probably is too or will be in the future plus I'll be able to refer back to this thread when I forget something. [emoji1787][emoji1787] So this thread is likely to be all over the map with random questions and observations as I go. I appreciate feedback and I know there are many knowledgeable fliers out there I can learn from.
I want the highest chance possible (within reason) of recovering my rocket. So to me that means I need two altimeters and GPS tracking in my AV bay. Right now I am thinking of the following hardware:
1) Eggtimer Quantum
2) Eggtimer Classic (I already have one)
3) Eggtimer Wifi switch (to control the Classic)
4) Eggtimer TX mini
Question - I see a lot of people use different types of altimeters when employing redundancy. I assume this is to avoid some freak event where both fail/malfunction for the same reason. So what about different models from the same vendor, like I have chosen? What's the view there? What if I were to use two Eggtimer Quantums? Would having two of the same altimeters be less risky than two different altimeters plus a wifi switch? So I'm adding a third component to introduce variety but an additional component adds risk of failure. (I'm pretty much set on using the wifi switches.)
