TAROT 650 frame holybro 6C

ArduCopter Copter 4.6

I have a Tarot 650 frame and a Holybro Pixhawk 6C. What motors and ESCs would you recommend using?
Currently, I tried using Hobbywing XRotor Pro 40A ESCs, but when the drone lifts off, only one side rises, and it flips over.

I’m using a 6S 11000mAh battery, and I also tested it with a 3300mAh battery.
I calibrated the ESCs through Mission Planner, and also separately by connecting only the battery and receiver – but the problem remains.

Is it a Pixhawk configuration issue, or could something be wrong with the ESCs?

Incorrect motor order, also check the spin direction of the props.

The motor directions were set according to the ArduPilot documentation, and also checked using Mission Planner’s motor test. In all cases, both the motor and propeller directions were correct: CW, CCW, CW, CCW in an X frame. Esc calibrated in variuos ways, connecting receiver, motors to battrery…
Via mission planner..

See if you can get a short video of a takeoff attempt. Try to be close enough to get a good view of the props.

This is how the motors spin when you check motor direction in mission planner?

A short video of showing the motor test via mission planner might also suffice without risking another takeoff attempt.

Yes, the motor directions are correct, everything was done according to the ArduPilot documentation. I suspect there might be something wrong with the ESCs. When I arm the drone in Mission Planner and open the servo output screen—where you can somewhat see how the motors are spinning—at low throttle, two motors show a PWM value around 1500, while the other two are about 200 lower, around 1200.

When I increase the throttle and try to take off, the PWM values briefly equalize for a second, but then those two motors’ PWM drops again. I’ll try to make a video tomorrow, because it’s really hard to explain. But this is the only way I can track what’s happening, and visually it’s also clear that two motors are spinning slower than the other two.

First do the semi-automatic ESC calibration

Then use MissionPlanner motor test to check if all motors spin at the same RPM. Arming and using throttle is not a valid test for this.

When connected to MissionPlanner, is the HUD showing level? And it moves the correct way with pitch and roll?
