Landing with the hiccup!

Hello
I am testing a quadcopter frame Tarot 650 Sport (motors Trarot 4114 with T-Motor 1555 blades) with a Pixhawk 4. I have a little problem during the landing. Some seconds before the automatic disarmed, the motors give an acceleration unbalanced at the back. The propellers give a short push up, I affraid by a reversal of the drone. Have you somes ideas about this case ?

Thank you

Hi
Can you share the log? It looks like a problem with the land detector, but without the log I cannot say more.

Hello

Thank you for your message

It seems me, the problem was corrected with modification of tuning setup in QgroundControl.

The value for “Manual Minimum throttle” is now 7%.

After landing, the motors are stopting automaticly after few seconds without the little accelaration.
