Drone wobbles and shuts off on takeoff
#1
I recently built a Tryo109 and have had many problems with it, finally I thought I had fixed all the problems, I armed it and it spun at a low throttle perfectly but when I raised the throttle the drone wobbled all over the place and shut off. Does anyone know how I would be able to fix this problem? CLI Dump:

I have been messing around with the drone and found out the motors spin at different speeds, does anyone know how to get the to spin at the same speed?

Are your props and motors oriented in the correct directions of rotation?

The motors rotating at different speeds is what will help the quad to maneuver around based on your stick inputs. How else will it yaw or roll or pitch?

additional unless you are using an analog motor protocol, there shouldnt be an issue from "different rotorspeed)
what motor protocol do you use?

Double check your motors are spinning in the correct direction and that the direction also matches what is on the configuration page. Also check props are correct orientation

All the motors are spinning in the correct direction and match in the configuration page, the props are in the correct orientation.

The blackbox log is very interesting, 2 of the motors barely turn on. Blackbox log:

if you move the quad, does the 3d animated model in setup tab move the same way?
in other words is your board orientation correct?

we allready checked:
-board orientation
-motordirection
-rotordirection


did you check the motormapping?
check each motor in betaflight configurator - motortab. the motor order is diplayed in the picture in motortabs

What's the electronics? If you are using a 4-in-1 ESC with a harness to the FC, I would check that harness and just makes sure all the pins are straight and connecting fine. The blackbox would suggest something about those two motors not getting proper signal or power. You could have check those pins in particular on the wiring harness.

Also check BLHeli suite or configurator to make sure all the ESCs are operating under the same settings (except for motor direction of course).
