Hi, i have an fpv drone and it has a problem that i cant solve.As you can see in the video below when i arm my quad and give it throttle the motors go up and down out of control without me moving the sticks. This happens with and without the propellers. Motor are going the right direction, they are mounted correctly the flight controller is well mounted i havent changed anything on the betaflight motor tab and it still does this! Please help
Drone specs
i flight xl5 5inch frame
Xing-e 2306 24500 kv motor
jb f4 flight controller
Jb 30A 4in1 esc

Here is the video:
 
This is common and expected. Don't use arm switch to run the motors on the bench if expecting constant motor speed use the sliders in the ui to send specific throttle to each esc. When arming the PID loop kicks in and tries to use the thrust from each output or esc/motor/prop to get the thing level or to hit a target angle, since no props on it has no control authority so it just keeps pushing one motor higher (whichever side is tilted down right now) if on the bench it will just vibrate and the gyros will pick up the vibrations as motion of the quad and will adjust motor output accordingly. Again trying to hit the current target angle or reduce the error/difference of current angle and target angle, this is what the PID loop does.
