I need help with some oscillations
#1
Hello guys. I just built my quad and I have some oscillation on yaw. The gyro isn't detecting any noise or anything but the yaw P goes bananas.

Should I just reduce yaw P? Can you help?

Thank you all

Your yaw P term does seem to be a bit strong. It won't harm to try reducing it to 50 from the current 70 and seeing what difference that makes.

What does your quad look like?

Ah, the ZX5!

I remember building mine. It was an insanely tight build and I'm still not happy with the fact that I ended up having to put the RX and VTX on top of the camera pod.



It's a absolute nutter with 4S and 5045 bullnose props though. Extremely quick and really agile.

It is indeed crazy tight




This is mine. I'm putting ws2812 leds on it right now

That makes me feel much better! Smile

What I'll probably do is swap out the VTX for one of the micro sized ones from Banggood. I reckon there's just about room for one inside the camera pod.

I use 5mm longer vertical spacers, makes the whole build much simpler Wink
