I've done a few flights with both of these altimeters in various rockets. Here are their apogee readings:
1. Estes Patriot with C5-3: JL = 253 feet. MicroPeak = 41.7 feet (12.7 meters) (likely glitch in the MicroPeak). During this flight, the JL was packed with paper towels in the nose cone payload bay while the MicroPeak was dangling in the "regular" payload bay (or maybe it was the other way around).
Launch conditions: cold and sunny with little to no wind.
2. Estes Patriot with C6-5: JL = 152 feet. MicroPeak = 146.0 feet (44.5 meters). Both altimeters were packed with paper towels in the nose cone payload bay.
Launch conditions: 48 degrees F and 61% relative humidity; little to no wind.
3. Scratch-built BT-50 AMRAAM with A8-3: JL = 103 feet. MicroPeak = 113.5 feet (34.6 meters). Both altimeters were dangling from the nose cone.
Launch conditions: 73 degrees F and 78% relative humidity; slight winds from the north
4. Estes Goblin clone with A8-3: JL = 62 feet. MicroPeak = 60.4 feet. Both altimeters were put into the nose cone payload bay, but not packed with paper towels.
Launch conditions: 81 degrees F and 68% relative humidity; slight winds from the north-west
That's only good 3 flights with both altimeters working properly (presumably), but it's interesting to see the seemingly random variations in the flight data.
Just thought some of you (ahem @BEC) might find this interesting...or not surprising and simply mundane.
