NORMAL ESC START UP PROCEDURE

1. Switch your Transmitter ON and set the throttle to its minimum position.

2. Connect the battery pack to the ESC.

3. When the ESC is first powered up, it emits two sets of audible tones in succession indicating its

working status.

* The first set of tones denotes the number of cells in the LiPo pack connected to the ESC. (Three

beeps (***)indicates a 3 cell LiPo pack while 4 beeps (****) indicates a 4 cell LiPo pack).

* The second set of tones denotes Brake status (one beep(*) for Brake "ON" and two beeps (**) for

Brake "OFF").

The ESC is now ready for use.

General Safety Precautions

Do not install the propeller (fixed wing) or drive pinion(helicopter) on the motor when you test the

ESC and motor for the first time to

propeller or pinion after you have confirmed that the settings on your radio is correct.

Never use ruptured or punctured battery cells.

●

Never use battery packs that are known to overheat.

●

Never use short circuit battery or motor terminals.

●

Always use proper insulation material for cable insulation.

●

Always use proper cable connectors.

●

Do not exceed the number of cells or servos specified by the ESC.

●

Wrong battery polarity will damage the ESC and void the warranty.

Install the ESC in a suitable location with adequate ventilation for cooling. This ESC has a built-in

●

over temperature cutoff protection feature that will immediately cut power to the motor once the

ESC temperature exceeds the 230 Deg F/ 110 Deg C high temperature limit.

Use only batteries that are supported by the ESC and ensure the correct polarity before connecting.

●

Switch your Transmitter ON and ensure the throttle stick is in the minimum position before

●

connecting the battery pack.

Never switch your transmitter off while the battery is connected to your ESC.

●

Only connect your battery pack just before flying and do not leave your battery pack connected after

●

flying.

Handle your model with extreme care once the battery pack is connected and keep away from the

●

propeller at all times. Never stand in-line or directly in front of any rotating parts.

Do not immerse the ESC underwater or allow it to get wet while powered up.

●

Always fly at a designated flying site and abide by the rules and guidelines set by your flying club.
