AP4.0.5 on omnibusf4pro on a ZOHD Dart XL, having flown many times before.
Did all the usual preflight checks – control and stabilization direction, gps lock, battery level, radio range check, cables and connectors, birds in the vicinity, traffic on a nearby village road, video in googles…
10 seconds after takeoff (more like still during taking off) I looked down to see telemetry on my Tranis screen (yaapu), a second later as I looked back at it the plane started rolling slowly to the left, not responding to commands. Hit the ground at full power, 90 degrees left roll some 80-100 meters away. The plane, as I think is obvious, is totalled and a write-off. Here’s a photo of the corpse.
Please help me understand what happened today since I can’t make sense of what the log tells me.
After the crash, back on the bench all the electronics did function as correctly – power, servos, FC…
Note: the rxrssi dropping to zero after the crash (clearly visible on the log) is due to me thinking I may have used the wrong sma adapter on the R9 antenna. So removed the radio antenna to check while walking to the crash location. It was the correct sma adapter.
Many, many thanks in advance!
