Hello all.... I have an eachine 250 pro with F3 board...the issue i face is the drone is not flying after 3 or 4 flights after the bootloader works are done and saved those in F3 board ....i am using a cleanflight v 1.2.4 which i did after watching some youtube videos ....please help me in this....some time one of the motors is not running ...sometimes all four working good....!

Calibration of ESC is needed perhaps.

Connect the FC to computer, keep the battery disconnected.,
In configurator go to Motors tab
Enable, I understand the risk,
Move the master slider to maximum position and connect the battery. Once the beeps are completed, lower master to zero and ESCs will finish their tones.
Disconnect the battery and connect again. Raise Master very slowly until the motors are spinning comfortably. Make a note of the value this is at.
In Configuration tab,change Min Throttle to about 20 points greater than the value you noted earlier.
Hit Save and Reboot.
