Most electric R/C vehicles up to recently used brushed motors but now many people are turning to brushless motors for their much higher power and because they require much less maintenance. However, the ability of the system to put out power is dependent on the quality of the batteries used. Due to their power, brushless motors are also used in bigger monster trucks.
Fuel engine sizes most often range between .12-.21 cubic inches. This is because of restrictions made by the main sanctioning bodies for radio-controlled racing. Many "outlaw" engines are manufactured larger than these, mainly intended for vehicles which will not be used in sanctioned races and therefore do not need to comply with these regulations. Engine size is related to the class of car; 1/10th scale on and off road vehicles usually are equipped with .12-.18 cubic inch engines, with 1/8th scale vehicles using .21-.28 cubic inch engines.
