Power cuts out with hard yaw... Please help.

Hi guys,
Kind of new to the scene, built my first quad a year or so ago and am now addicted. I've built a few of them but this is my first 4S build and the first I plan to put FPV on. I had never tuned any of my other quads, but am experimenting with tuning on this one. When testing various PID's I noticed if I use the yaw aggressively, the power cuts for about a second to all motors, then comes back after about a second. Any idea what could cause this? Is it software or hardware?

Also if you guys have any tuning tips, feel free to share.

If it helps, I noticed it only does it at FULL yaw left. I can hold it almost all the way left and its fine, but as soon as my joystick hits the side of the controller, power cuts. Doesn't cut at all if I yaw right.
 
Would running through the transmitter set up wizard calibrate it? I use LibrePilot. Taranis X9D transmitter.
If not, How do I calibrate the transmitter?

Thanks for the response!
 
What jackson said sounds like a likely cause, if the end points were configured wrong in the Cleanflight software or in the Tx's settings you could experience such a problem.


If that turns out not to be the cause, just currious to see if you have any blackbox log of the event? The data could show the problem if it were something odd, or if it is something to do with voltage cuts I
d check the VBAT varible to see what it may yeild.

This is another problem that it is probably not, but could yeild similar symptons; if the motor configuration settings were not the usual, or if you had some sort of mixing setup you might experience such a problem.
 
Hello Everyone!
Thank you for all of your help, problem solved! What Jackson said was indeed the problem. I think what caused the issue was during my transmitter set up wizard, the part where it instructs you to move the sticks to all the furthest points, I must have not went all the way with my left yaw, and it therefore, was unrecognized.

All set now.
Thanks!
