(((((PROBLEM FIXED)))))


Hi there 
Recently I upgraded my 7 inch 4s quad to 6s and I've been having some difficulties.
After upgrading I noticed the quad to have horrible twitches making it unflyable. 
All components are 6s compatible.
It has Kiss FC v2

To make sure something I hadn't broken something without realising I plugged in a 4s and tried it... smooth as butter. 
Iv'e added dampeners to the flight controller, and motors, but haven't helped the problem.

Problem is not apparent with props are off , it only arises when on. 

here is a video of the problem 


thanks

What motors is is that and what KV?

KababFPV had an interesting video on this topic where he had an example where a set of motors run fine on 3S but on 4S they twitch: https://youtu.be/0H2gm6v6dZQ?t=267

Thank you!
I managed to fix the problem after watching the video I tuned the D way down , It has fixed the problem.
