How to adjust the throttle value of black sheep remote control?

The black sheep of the remote control should calibrate the rocker before adjusting it. The adjustment range cannot be too large. After adjustment, check the winding degree of steel wire. It is best to control it within a suitable range. Too tight will increase the idle speed, and some of them are fixed with nuts. Therefore, loosen the fixing nut with a small wrench first, and then make adjustment. If it is an electronic throttle, it can't be adjusted by itself, and it needs to be adjusted by special instruments in the repair shop.
