So I am having issues with my synergy 766 with the Xnova 4535 and kosmik 200. Head speed seems to drop a bit and I get a nasty 90 degree kick on sudden collective punch outs. I have made sure that I set mode 1 then mode 4. I had this esc in a goblin before this although with a different motor. What settings do I want to start messing with in the programming to mitigate this issue.

Have you tried Gov store, something I learned recently for the Kosmik.

No option for external gov with Kosmik.

90 degrees means you go from looking at the tail of the model to full side on. That's more than a kick and in the direction of nose left means the tail is letting go. Make sure you have enough tail gyro gain and tail blade and you can try increasing gov gain a bit using the ProgUnit.

It sounds to me like your gearing is too steep for the head speed you are running and you have too much collective pitch.

What is your gear ratio, motor KV, headspeed and cell count you are running?

Hmm I guess so. Would have been nice to know the fix so others can benefit from it.

Talk about a long time in between posts. I have not played with this model since I had the issue. Looking into some other posts, I made a few adjustments to the Kosmik. I am actually planning to fly it soon and see how that goes. I also have a tribunis that I may install if problem is not solved.

Reading back, doesn't sound like an ESC problem. I'd guess tail precomp in the FBL or too much pitch on your main blades.
Does it happen with a mild punchout?

If you are going to run xnova with kontronik set the timing to fixed and set at 18 degrees this is the setup I have been testing for the last week speed control and motor are much happier.
