motor acceleration and ocillation

[menghaozhao]

Not installing propeller I'm trying to remote control my motor on the desk.

My motor begins accelerate continuously as soon as the throttle is pushed a little over 1000 and stays there.

When lifted they also oscillate violently

when the motor is controlled by betaflight, they are stable.

I double this is due to the PID too strong, or accelerometer / gyro have issue. But I did caliberate accelerate on betaflight

flight controller and esc t-motor f7 + t-motor f55A + taranis QX7

Running without props is meaningless and will do weird stuff like this, it's perfectly normal. Check the directions are correct, but besides that it's all you can check without props.
