Hello,
I received my new flight controller(Matek F405-CTR) yesterday, flashed the firmware and calibrated sensors. Finally, everything was done so I decided to try to fly it. Firstly I gave too little throttle to see if anything go wrong. It doesn’t seem to me it reacts correctly, so I hold my quadcopter with my hand to feel the thrust vector. I gave a little power with holding it, responded very badly to movements so I was about to stop it, then suddenly throttle increased without my command, not a small %5 increment, it went for %80 power from %20 I guess. I cut the throttle but it stopped after a while and probably it detected as crash, not due to throttle cut. So I would like to see: Why throttle increased suddenly? Why it acts very bad? But the priority of course sudden increment in the throttle. Log is available as an attachment. Thanks. 12 1.01.1980 02-00-00.bin (792 KB)
You had a GCS failsafe and it went into land mode.
Holding a quad with props on is never a good idea.
Thanks for the fast reply. Failsafe should be responded with RTL but GPS wasn’t available so it just tried to land, correct? I am using APM 2.6 since 4 years, due to older firmware(s) I can be not experience this or just didn’t enable gcs failsafe, anyway it makes sense. However as I see motor output pwms hitted around of 1700. 2000 should be maximum value. It is pretty high for landing, isn’t it?
Obviously it’s not a good idea, but there’s not any better options I guess. Once it almost about to cut it’s own battery and that’s pretty much worse I suppose.
Do not hold it, the control loop is going to counter act you movements. Just let it fly, it will behave better.
That’s a good point but it’s a unexpected behaviour. I don’t remember anything like that. I don’t know if these are available for reading in somewhere but I should take a look.
I had pretty bad experiences when flying indoor (shouldn’t do, I know but I don’t have a free space in outdoor, only the flight site -which is my house too but pretty far- has enough space)so I have to fly test it in indoor. disabled failsafe and corrected motor order. Now it’s flying correctly, thanks…
