Phantom 4 yo-yo effect while flying

[keithwebb]

I am getting a yo-yo effect while flying. The drone sounds like it is reving a engine sometimes and the drone rises and falls 5-10 feet sometimes. I did IMU calibration, compass calibration, firmware update, and sensor recalibration. None of these seem to help. Any ideas what else to try?

Did you use a gimbal guard?
Or maybe your downward vision sensors are dirty or obstructed

I did have a gimbal guard I used did that cause this

These are brand new props

There can be a issue if you use a gimbal guard as they can interfere with the sensors check out some YouTube videos regarding phantom/yo-yo effect

I no longer use the gimbal guard and still get the yo-yo effect
