Hi all, I currently build free flight drone, and I have some problem. 
Im using the speedybee F405 wing flight controller (It sound dumb but I can not find any cheapest FC broad and have plug and play in my country). When I fly test, it does not fly straight up, when i check the rpm of each motor in Mission Planner it show nothing about it, but in the servo output tab, it show a bit of information as picture below. After I searched on google, apparently I did not set up the PWM TYPE. So my question is what is  hobbywing 40Av2 skywalker ESC type, and why is it written on the broad is UBEC? how can i change the rpm for the BLDC motor?
this is my set up info:
FC: speedybee f405 wing
ESC:hobbywing esc 40Av2
BLDC: A2212 1000kv
Battery: 3s 2300mAh, 45C

I can not see the image, use igmur and paste a link should work well.

Ubec is a voltage regulator. It might have a regulator which provides 5v, to supply a receiver or a flightcontroller.

I just updated the post, I don't know why I did not upload it at the time I wrote the post. but after research, the hobbywing esc 40Av2 just setting up normal PWM type. But how can I read and change PWM signal and RPM from each ESC in mission planner

The gyro does manage the rpms next to the throttle value.
You need to choose pwm as motorprotocoll.
For analog pwm, you will need to do throttle calibration on esc startup once

It might be better to flash inav or betaflight. What software do you use?

sorry for the late reply. I'm flashing ardupilot, so should I flash Inav or Betaflight or keep using mission planner and try to do throttle calibration because I don't see any calibration for the throttle?  I think because this FC board divides PWM output into different groups so that I can not do throttle calibration?

And I dont know why, when i push the throttle RC up about 50% the PWM show that 2 motor spin faster than the other

I have no experience with ardupilot. It might work either.

Here is some info about esc calibration.
