Hi Tanjuuro, Welcome to the forum!

The major reason for quad to flip on take off is due to incorrect motor layout connection.
Make sure you have selected the correct Quadcopter frame ( X type), then check the motor layout page and connect your esc accordingly.

Hope that works out for you!

there could be few reasons for the problem you are facing bro,

1. not proper orientation of the motor or the wrong wiring of the motor for which I have attached a image showing motor mounting no. and their sense of rotation of the motors.

2. there are a lot of cheap variables of KK boards whose performance is noway even close to the original one in that case search for a YouTube channel OM HOBBY, he has videos in this regard.

3.try recalibrating the esc and the remote gimbals
