Strange things happens to me yesterday with Arducopter 3.0.1 and I am thinking about “jamming” my quad by someone else, maybe this is just in my mind. See logs and TLogs attached.
APM2.5, AC 3.0.1, Tx Spectrum 2.4Hz, 433MHz telemetry, no FPV
I was playing with my quadX yesterday for some testing (Loiter, RTL, Stab), was little windy.
First 2 flight were normal, no issue. On 3th flight, when I was on the “air” I did notice a guy behind me with playing (I believe) a Tx remote control with extended antenna (not 2.4GHz), but longer antenna. At some moment, from stabilize position at 6 m altitude, my copter starts to drift and loose altitude and crash in field. I was in Stabilize, I did check that 2 times and see on log also. During this time, I had not any control on my Quad, I did try to roll/pitch and increase altitude, since was loosing altitude fast. No control!.
After the crash I did ask the guy what is he doing there, is an empty field and always I was alone.
He said he crashed his RC copter one day before and did come for finding it. But I was wondering why you need your Tx with extended antenna, when you are looking for your copter.
I do suspect 3 scenarios: brown-out, mechanical-failure, or “jamming”. From the log I did not notice any brownout, HW voltage was OK, battery voltage was 12v after crash (I did check that).
Could someone please try to see which of those 3 scenarios could be the answer?
I did parse all the situation from link below regarding the diagnosing.
