SMALL ESCs (Electronic Speed Control) for brushless motors

The ESC controls the brushless motor using the R/C radio's throttle function.  These also include a BEC to provide 5V power for your R/C receiver and servos. In most cases no programming is required. 

Available models change often along with out stock - check this page to see what we have to offer.  

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

Here is information for the popular SimonK 10-amp ESC. 

NOTE:  there is no low voltage cutoff and no over temp cutoff on this ESC.  Best for motors 2000KV and less. This ESC is NOT recommended for very high-KV motors. 

Mfg. states:  High efficiency 100% N-FET design.  High accuracy with Crystal Oscillator (Temperature won't affect the PWM operating range like other cheap ESC's). Super high refresh rate & no buffering of the input signal results in more than 490Hz response rate. 16KHz motor frequency gives fast motor response, and quietest operation as well (no 8KHz squeal).  

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

What amperage rating will you need?  It 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! Too many amps can burn out the motor or ESC.

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