Greetings All…this is the first I have experience this…when we were out testing the other day, during the end of the testing (4th mission with this airframe), I randomly experience RSSI dropping from its normal value around 200, to almost 0. This would put our craft into a failsafe, then RSSI would increase and go back to the normal operational level. This happened a dozen or so times, as I was bringing the craft home. Could heat cause this? We did have the ground RFD unit in a makeshift black pelican case, without the best cooling, and it was sunny and ~90 F. Any other ides? I have posted a graph of the RSSI and remRSSI…this is the first time this happened and was the last mission of the day.
