copter = helicopter, use drone.
blanch is not the correct term, use to tin which is widely used.
Flat cable is used but I beleive ribbon cable is more common (not sure)
Unclear sections (did not understand in russian neither, coming from an unadviced reader it might be usefull to clarify those points)
- l.61 "the red and black wires are to be tinned on both ends using tweezers" (did you mean soldering iron?)
- l.82 "disconnect the power and move yellow jumper to the other tweezer" (did you mean pins)
- l.145 "thus, it will be clear which motor is controlled" (unsure if by going through the procedure we activate the motors individually or by setting the throttle to 10% we simply see the direction of spin as it's slow)
not linked to the proof reading:
do you power the rgb strip directly from the raspberry pi with pin 40 (gpio 21) ?because it can be dangerous as the led strip is drawing x mA or even x A, and the RPI is not designed to withstand such currents (I beleive not more than 500mA), be carefull :o
