RC cars with a metal main pair

 

— the main pair is two gears, one of which is located on the engine shaft, the other is on the transmission shaft. It is one of the most important components of the machine, because. transfers torque from the engine to the transmission. Loads on the main pair can be quite significant, especially for off-road and racing riding; therefore, for professional stunt and short-course models, the presence of metal gears is very desirable. At the same time, models for everyday recreational driving in most cases do well with a plastic main pair (especially since it costs less).
