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. The picture is a representative sample (10amp size), but the size and shape can vary.  We offer several different ESCs that you may select:

20 and 25-amp ESCs - these are for larger motors than what Rabid Models uses - Except for the 3000kv OMG motor which does need the 20amp ESC.  

The 12-amp ESC is our standard for our 24-gram brushless motors when using a 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 needed). For the 1300kv 24gm motor, you may also use the 10-amp ESC but the 15amp is the same physical size and price.

We recommend the 10 or 12-amp ESC for the smaller 17gm and 10-gm brushless motors that we sell.  

The 6-amp/7amp ESC is 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! The 7-amp unit is made for 1 or 2-cell Lipos.

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.
