"it probably wasn't just a stray RF packet, as the channel levels change afterwards from the previous "tx off" values and stay there. Perhaps a power spike that put the receiver in a bad state? How is the receiver powered? How is the…"

"Tridge, thanks for looking at this. I can 100% say that step 2 was not as a result of turning on the transmitter.  Now i dont know if i trust my setup anymore or if this is a one-off error that will never happen again....."

(Mission planner automatically appears to draw a return to start point as a waypoint - so the distance does not reflect my actual mission distance - sinnce my starting point will not be the same as my landing point)Does verify Alt work - I am using APM 2.6 (i.e not PIXhawk) with its latest available firmware. - Do i have to check that value before i start…See More
