For those of you that are running a Zlog, Eagle Tree or other units, I have a few questions. Have you had to take steps to deal with rotor-wash affecting your readings? Have you verified your altitude readings? Do your readings fluctuate significantly on the ground?
My Eagle Tree telemetry gives very odd readings on the ground. Once I power up the telemetry my altitude reading started at -1' and continued to decrease to -100' over a period of a few minutes. After roughly 30 - 40 minutes it read -286' (Indoors, no wind, 72 MHz transmitter turned off).
Has anyone else experienced this? The odd thing is that the readings seem reasonable after a flight, although I have not verified them. My flight data recorder sits inside the canopy but is not isolated from the rotor-wash.
