Very strange flight today. After completing a number of missions with 3 to 4 waypoints followed by picture perfect RTL landings - upon re-arming in Stabilize mode, the quad went to full throttle, leaped into the air and flew away. It flew over an office building and went out of sight. Somehow, it landed a couple hundred yards away in a parking lot with minimal damage. After it took off, none of my inputs into my Spektrum DX7 seemed to effect the flight. I perused the logs - I’m not an expert - but didn’t see anything extraordinary. I’d appreciate if someone could look at the logs. My biggest concern is why the quad would take off by itself immediately after arming. Logs attached. Thanks!!!
The copter seemed to do exactly what is was told to do via the RC inputs.
The file Flyaway1 shows that throttle out followed throttle in, as well as the pitch and roll inputs.
Backing up in the control chain a little farther, the RCInputs file shows the logged RC inputs. It shows in particular channel 3, throttle, going max. Thus, at least all the commands were coming from your receiver. Whether the receiver did this on its own, or followed your inputs, that’s for you to say. The inputs were varied which looks like you were trying to fly it.
I actually had this same problem! However, my logs show no throttle input from the controller. Please review my logs below - 3DR looked at them and couldn’t find why it took off after being armed but before throttle input.
I have a 3DR X8 and a Pixhawk, and am using Mission Planner.
