ESC – ELECTRONIC SPEED CONTROL

An ESC regulates the power from the batteries to the motor. It must be properly selected in order to be able to handle the current draw demanded from the motor.

It is recommended to choose a high quality ESC. In most cases, once the cell count and motor is selected, it should be quite simple to select an ESC from here. The ESC must be capable of handling the maximum continuous current of the motor and the LiPo cell count selected. For most setups 1/10 scale RC’s will require an ESC that can handle 2 or 3 LiPo cells and 120A continuous current. For 1/8 scale, an ESC that can handle 4-6 cell LiPo and 120A continuous current is needed

When using more than 4s LiPo, it may be necessary to disconnect the BEC on the ESC and use a 4 or 5 cell NiMh receiver pack or 2 cell LiPo with voltage regulator. This will be specified on the ESC manual whether this is required or not. To disconnect the BEC on the ESC remove the center wire on the ESC to RX lead. It can be pushed out with a pin and replaced later if needed.

Follow motor manufactures recommendations for motor timing. If unknown, keep low. For example Neu 1D motors must always be set for low timing.

Voltage cut off is standard at 3.0v per cell. However, if the power setupl you are using does not draw a lot of power it’s recommend raising this value higher in order to stop a run a bit earlier leaving some capacity in the pack.  In most cases many raise this cutoff to atleast 3.2v per cell.
