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). The 1300kv 24gm motor may use the 10-amp ESC but the 12amp 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!

ESCs can vary in physical size depending upon availability, but in general the larger-amperage units are physically larger. Some of them have connectors already installed. some do not. JST plugs, Bullet connectors, propellers and motors are all available separately in our catalog.
