Motors spin different speed
#1
Hello guys. I got a problem. I don't know it's a normal or ubnormal issue. When I'm raised motor master in betaflight motors tab the motors spin well also when Im arming via tx then raised the throttle, the motors spin well at same speed except motor 3&4 that spin little bit different(i guess it because the gyro). But when im activated the air mode, then im raised the throttle the motors start spin at different speed. Then when my throttle is zero the motors still spin with different speed. So when Im tried my quad at the field my quad got flipped again and again. Im running fvt little bee blheli opto. I've calibrated my esc. Im running multishot.

Don't arm the quad without props on the bench. It's meaningless!

If you arm, the flight controller thinks you are trying to fly. If there are no propellers, the flight controller won't see anything happening when it tries to move the quad.

If the motors work fine in the motor control tab, they are working. You don't need to do any more testing. Put propellers on and go fly!

I've tried to fly. But when i'm just pulled the throttle my quad went to left it self.

What ESCs protocol are you using? Have you calibrated your ESCs?

Sorry I didn't read OP carefully. You did already mentioned you protocol.

You can swap ESC to different location and see what happens. I would swap 2 with 3. If quad flips right, then esc problem.

Some really basic questions:

Have you confirmed that the motors rotate in the correct direction?
Have you confirmed that the flight controller's motor positions match?
Do you have the correct propellers on each motor and are they the right way up?
Have you confirmed that the 3D model in the configurator moves to match your quad?
