I need help to find out my problem.
I have a quad on a sk450 frame with apm 2.5, FkSry tx/rx, AfroESC 30a, 28-30s 900kv motors and neo-ublox gps.
I crash my quad last week. Apart the four propellers and some nylon spacers and screw, everything's else seems to be on shape.
I then rebuild my quad correctly and change the propellers. Before I used standard plastic props and now I putted carbon props.
My problem is now i'm not able to run the quad smoothly. I did a 3-4 minutes tests flight by keeping the altitude at max 8-9 feets and three times while the flight I got a "crazy" quad. I attached the IMU log...as you can see I got peak vibrations 3 times corresponding with my "crazy" sequence.
So now, i'm trying to find what causing this strange behavior. Before, with my setup, I have perfect vibration value. My APM is still on a fiber shock absorber anti-vibration set.
Is there a possibility that with my crash I damaged my motors and it cause more and more vibration on my quad ?
I'm beginner in the quad world and was very happy of what I done with my quad...but now, I'm disappoint because i'm not able to find out my problem :|
What stresses me a little is that when I order the pieces I have to wait a 3 weeks for the shipping so I would like to be sure sure as much as possible before buying pieces.
Many thanks for reading.
