The ESC controls the brushless motor using the R/C radio’s throttle function, and it also provides 5V power for the R/C receiver and servos. In most cases no programming is required. The picture is a representative sample (10amp size), the size and shape can vary. We offer several different ESCs, you may choose from our stock:
25 and 20-amp ESCs – for larger motors than what Rabid Models uses
We recommend the 15-amp ESC for the 2000kv and 1700kv 24-gram brushless motor when using a 3-cell battery under high load.
We recommend the 10 or 12-amp ESC for the 1300kv 24-gm brushless motor, the 17gm brushless motor, and the 10-gm 2000kv brushless motor.
The 6-amp ESC is appropriate only for the smaller 5-gm and 10-gm brushless motors.
The amperage rating you need will depend mainly on the propeller you select – propellers with higher pitch and larger diameter will draw more amperage! Using a 3-cell pack will draw more amps then when using a 2-cell pack!
In general, higher-amperage ESCs are physically larger and heavier. However the ESCs can vary in physical size depending upon availability. Some of them have bullet connectors already installed – if not, bullet connectors will be included in the package for the ESC and motor. The power wires require a connector for the battery, not included. (These ESCs typically are used with a JST socket to connect the battery.)
JST plugs, Bullet connectors, Propellers and motors are all available separately in our catalog.
