Erratic yaw to right

[Philuk46]

Hi All,

Ive decided to get back into the hobby with a new build 130 frame. All seemed well until first test and any test after with the little bugger jumping to the right in yaw (worse on a full battery charge)

4 x new littlebee ESC 20a, new F3 mini, 4 x new 1306 motor and I’ve no idea where to go from here.

tried adding a small dead band to yaw etc

many suggestions would be most welcome. I’d add a short vid but no idea how

Hi upload a video to YouTube then copy paste the link on here
Check to make sure there is no mixing going on in transmitter and all trims are centred what does it do in a hover does the jump only happen in a yaw ? , is the FCB mounted to tight or to loose ?

Thanks for the reply. The FC is tight in the frame using the plastic nuts. I’ll see if I can get the vid onto YouTube ASAP. When trying to hover the quad jumps to the right in Yaw. I’ve added a small dead band in case it was from the Tx but still there. Tx and Rx seem to be working fine when viewed in cleanflight.

Might be kinda counter intuitive but try loosening stack screws so FC can move a tiny bit in there if have em add rubber grommets under/above the FC or in screw holes ideally so screw not rattling the gyro on the FC.

Alternative can try adjusting the filters to get it to ignore the knocks on the gyro from the screws mounting it to the frame.

I’ll give that a go thanks.

Thanks wafflejock that was my thinking too

RESOLVED…Thanks again for the advice. I’ve used some slighty longer stand offs and some rubber to dampen the FC. Hovering perfectly now and ready for some real practice.

Glad you got it sorted enjoy flying
