Hi Kirk, saw that you are strugling for outrunners for model air planes, cars or boats. Look at http://www.hobbyking.com/hobbyking/store/index.rc for quite good and afordable motors and ESC's. The number of rpm's depend on the type of motor and the aplyed voltage. You can calculate this by multiplying the voltage with value of kv (e.g. 1024kv). For the ESC take one that has some reserve, meaning when the motor takes a maximum current of 60A take an ESC for 80A continuous or more. Cheaper motors also have cheaper bearings. Some motors have a fan mounted on the housing. These are normaly designed for helicopters, because in a helicopter you don't have a cooling air current. Just as an example http://www.hobbyking.com/hobbyking/store/__9021__Turnigy_Typhoon_450H_2215H_ Heli_Motor_3550kv_450_class_.html.
