I just flew both of my Missileworks RRC2-mini's for the second time. Two were used for redundancy on the flights. On both flights, both altimeters read the exact same altitude, right down to the exact foot. Is this normal, or a coincidence? I expected them to maybe be within a few (10-40' ?) feet of each other. Also, the flights were completely different in every way. The first flight flew an Intimidator 5 to 3245' starting at ~5000 MSL (colorado) and one flew a 1/4 scale nike to 2673' starting at ~0 MSL (florida).
Seems ridiculously accurate to me, although I know thats not the true altitude, due to nonstandard pressure/temperature fluctuations.
