Today I did my third small hover test with my (first) 250 build. All was ok until about 5 min then the copter suddently increased throttle (not to max, I guess it just got stuck in the latest transmitter command) and flew over my head over the neighbors garden, still gaining altitude. First I put the throttle stick to minimum but it didn't respond at all and once I realized I completely lost control over the copter I switched off the radio control. Eventually the copter came down but I don't know exactly if it was because of me turning the radio off or because some kind of timeout. I found it in high grass, nothing is broken at all, a bit suprising considering the barometer says it went up to almost 30m.
Because it was just a small test I didn't have any fail safe set up, but afterwards I checked that the receiver goes down to 900 (1075 is throttle all down) once I switch off the radio. So that will most likely be the cause for the fast descent. But why did it fly off with me only 3m away?
RCIN tells me all channel values start forming a horizontal line a moment before the ascent. It seems that all control suddenly freezes. RCOUT still has some variation, but less than before.
If this is the result of lost contact (maybe bad antenna orientation or interference with my 2.4Ghz wifi), why didn't it failsafe to 900 until I turn the whole thing off?
I have a Turningy 9x.
Does anyone who knows how to read the logs have an idea?
Thanks in advance!
