Thanks.

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

not 100% ok.... seems we need noise sensors filter in the code... does 2.7.1 include it? chris anderson can you confirm us if still filtering has to be integrated? i replaced 4 motors and props and tried some foam isolators but not perfect yet..sad

I have the some frame and it flew fine on 2.6 but with 2.7.1 it is doing the same as yours but much worse. My board is foam taped direct to the centre plate at the moment but what would be the best way to fit it to stop vib ?

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?

Thanks...

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

Hi,

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.

Hello R_Lefebvre,

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.

Greetings

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.
