Jumpy Throttle!!!

[MillDude]

Hello,
I'm completely new to RC and recently completed my first mini quad. I took it out for my maiden flight and it flew fine except for the fact that the throttle would jump by its self. It would jerk upwards almost a foot and the motors sounded like a dog barking when it happened. It wasn't always all 4 motors at the same time, most of the time it was one at a time. I would appreciate any ideas on why this would happen. My setup is:
-ZMR 250 Frame
-Rotorgeeks SSD FC
-Matek PDB-XT60 w/BEC 5V & 12V
-Sunrise Cicada 30A BB2
-Rotorgeeks 7075 Series 2204 2300kv motors
-HQ Tri-Blade 5x4 props
-a buzzer
-an addressable LED strip
-FrSky XSR Receiver
-Taranis Q X7,

Thanks

Can you post some pictures of your build?

Usually this kind of odd behavior is caused by vibrations getting to the gyro. I'm not seeing any obvious causes in your build, but the first thing I would try is soft mounting the FC. Rotorgeeks has these that work very well - https://rotorgeeks.com/anti-vibration-standoffs-m3-4pcs?keyword=vib

Ok thank you I will try that!

Something else to try - if you're running a DSHOT ESC protocol, try MultiShot instead. I was having similar problems with those ESC's and that ended up being the fix for me.

Edit: You'll also have to calibrate the ESC's using the motors tab in Betaflight

Ok I’ll try that too! Thanks again!
