Horsepower - HP --

During the 'olden times', horsepower referred to how many horses it took to do a job (such as pulling a stump). Today, it refers to how fast we can potentially go and how high our wheelies can be. In essence, horsepower is a measurement of potential energy (i.e. work done / time). For electrical motors, 1 HP = 745.7 watts of potential energy per second. For nitro and gas engines, 1 HP = 550 ft. lbs. per second. HP = torque x rpm / 5,252 - so even though a standard servo and a standard nitro engine may both produce around 100 oz. in. of torque, the engine spins at a much higher rpm than the servo (about 30,000 rpm compared to about 60 rpm), which gives the engine that much more HP.
