SMALL ESCs (Electronic Speed Control) for brushless motors

The ESC controls the brushless motor using the R/C radio's throttle function, and it also provides 5V BEC power for the R/C receiver and servos. In most cases no programming is required. 

Available models change often - we offer a number of different small ESCs that you may select from:

20-amp ESCs - these are for larger motors than the regular Rabid Models motors - for example the eMax motor that we sell needs the 20amp ESC.  The 20-amp ESC comes with connectors.

The 12-amp ESC is our STANDARD for our 24-gram brushless motors (1300kv, 1700kv) when using a 2 or 3-cell battery under high load.  This ESC comes with 2mm connectors installed and an XT-30 battery connector (the connector can be cut off if you need to change it). For the 1300kv 24gm motor, you may also use the 10-amp ESC but the 15amp is the same physical size and price.

The 10amp and 8amp ESCs are appropriate for our 17gm and 10-gm brushless motors that we sell, with 2 or 3 cell batteries.

The 5-7amp ESCs are appropriate only for the smaller 5-gm and 10-gm brushless motors. The 6-amp unit is not as physically small as the 7-amp unit! These are for 1 or 2-cell Lipos - do not use with a 3S or it will burn out.

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 connectors already installed. some do not. JST plugs, Bullet connectors, propellers and motors are all available separately in our catalog.
