I'm flying a DJI Flamewheel 550 with a APM 2.0, it's flying very nice. and using the DJI esc's and engines.
Sometimes in flight one engine is quitting the job. Only for half a second and then back to work.
Just enough time to recover :) The hardware seems ok, i checked the connections of the esc and the motor connections .. Is it possible thats it a software issue?
The problem occurs sometimes in hover and also when flying a bit rough ...
Ok thanks. I'd very much like to see logs and/or videos if you have them or can get them.
joo, i found the problem! :)
all my engines (stock engines and esc's) from the Naza Flamewheel s-550 had problems with the esc connectors.
the trick was, i put a drop of soldeer on the tip of the engine connectors and now the problems are disappeared :)
see circle where i put the soldeer.
(don't put to much on it, or the wont fit anymore) :)
Wow. I would not have guessed that actually. So I guess the little round bit at the top was too loose. fantastic that you figured out the cause!
I find those springy metal things start to flatten out and lose their spring and then the connection is loose and unreliable. I've taken an xacto and put a hump back in them before, but always wondered if they might just break one day due to fatigue.
Oh no... here we go again with bullet connectors failure/issues...
and people still ask why I always recommend to remove them and solder directly the wires?
Yes it only happen to some people but really why take the chance?
It is one failure point easy to fix, direct solder!
Ok yours did not cause a crash that costed you a lot and you were able to isolate and see/fix the issue. But I am sure a lot of strange behaviors/crash/flips are due to these getting slightly loose cause either a micro surge or a massive flip.
Overall I am glad for you that you got it sorted out. Now go have fun!
During my first flight check I was lucky and noticed issues with the 3mm bullet connectors. Here's what I did.
I tinned the connectors with solder. It's a tight fit, but it works.
During the maiden fligth one engine makes some strange noise, please check the follow video 1.47 , 2.19 and 2.45 min.
I am using 95% default parametes just decrease the P rate to 0.1 and increase P stab to 5.0.
4S, T-motor 28-20 830 Kv,props 11x5 .
any advise also fine tuning please let me know.
Decreasing RATE D to 0.002 and P to 0.090 ,after 4 short test all OK.
thank you so much for your advise.
Jos, can you send me what your final tunings were for your hexacopter? It would be a good place for me to start. A screenshot of your settings would be perfect.
