Im having micro (in duration) glitches/ flickering (micro accelerations) when fliying my new apm2 X quad, in order to identify if they are radio problems (they are not!!) , motors, vibration, PID adjustements , or the apm2 itself, I want to ask :
is there any relevant info in the logs that i can analize? how? i ve changed 2.4 receiver and placed gaui board, and still the same random glitches. thanks for any clue.
i can generate logs (after solve problem not inserted memory) if needed
*My HK frame has integrated PCB http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...
* XQUAD - 8045 props and 2212-15 930kv motors HELP ME PIDS Are defaults!
* Futaba 7cap 6 modes-
* ADC 2.7.1
UPDATE: it is not radio problem , I ve just replaced APM2 with GAUI330X electronics and works 100% free of any glitch. Frame is also ok (a little heavy but ok). Something in APM2 is causing those microglitches HELP!!
solved! *- custom antivib*-
I am having the same problem. How do you solve it?
It is seem that the APM2 is muuuuuuuuch more sensitive to vibrations than any other fly electronics that i have tested, so i tried to minimize and insulate the vibrations everyehre i could. just that. rest seems to go fine, loiter is great. goog luck
Finally solved!!! no vib at all, no more need for filtering in the code...
How did you isolate board from vibs (what material)?
Could you send a photo to have an idea of your solution?
I still have this problem. Have to put APM in the box and fix it with double sided tape mounts. Please help us. If possible post a photo
I do not think the solution is to find suitable materials to isolate vibrations from the APM, with firmware 2.6.0 when there were no such problems. Why do not you do a downgrade on the Mission Planner to be able to fly safely, and allow time to correct the bugs of the 2.7.1 firmware.
Fabio, I suspect what may be happening here is that changes were made the to Alt_Hold code which makes it perform better, but also makes it more susceptible to vibration. So, vibration damping will help with 2.7.1. Really, it's something that should be done in any case, but this makes it more important.
We believe it is important to improve the stability and Alt_hold the road taken is correct given the evidence of the movies, but should not affect the stability, security of the vehicle. The bug is discontinuous and suddenly, bringing to the pilot error and creating a situation of difficulty in driving the quad.
From my experience, the problem does not cause the copter to be difficult to fly. It's totally controllable. For me it's only an annoyance, or a curiousity. I just wondered why it started doing it.
