●Never use ruptured or punctured battery cells.
●Never use battery packs that are known to overheat.
●Never 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 heat cutoff protection feature that will immediately cut power to the motor once the ESC tempera-
ture 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 while powered up.
●Do fly at a designated flying site and abide by the rules and guidelines set by your flying club.
