5. 0mAh Ni MH 4 8V receiver battery EXRB100 or similar 2 Expert Standard Switch EXRAO50 or similar PLEASE READ THESE INSTRUCTIONS IN THEIR ENTIRETY BEFORE USE Before you connect your ESC and begin flying take a moment to look it over The input power side has a black negative and red positive wire along with an E flite EC3 Male Device Connector The motor side has three 3 5mm female gold bullet connectors The black and red wires with the EC3 DEVice DEV Connector will connect to your power battery The red wire connects to the red wire on your battery pack the black wire connects to the black wire on your battery pack If the wires are reversed the ESC may be damaged YOU MUST ENSURE THAT YOU CONNECT THE BATTERY POLARITY PROPERLY TO PREVENT DAMAGE TO THE ESC Reversing polarity will void your warranty so always double check this connection You may need to solder an E flite EC3 Female Battery BATT Connector EFLAEC302 to the battery so it matches this speed control The throttle lead connects to the throttle channel on your radio receiver WARNING For your safety when checking the startup function of the ESC or making programming changes please remove the propeller to prevent any potential injury You should always treat the motor and propeller as live and dangerous remembering it could start at any time and keep any body parts clothing and tools clear of the propeller arc NEVER LEAVE THE BATTERY CONNECTED WHEN NOT FLYI
6. NG THE AIRCRAFT AND ALWAYS REMOVE THE BATTERY FROM THE MODEL BEFORE CHARGING AND WHEN FINISHED FLYING When flying in hot weather we recommend checking on the condition of the ESC battery and motor after each flight You may want to consider letting the electronic components cool to near ambient temperature between flights We also recommend throttle management when running near maximum levels of current draw It is not recommended you fly an entire flight at full throttle If this is done it is possible to cause permanent damage to your motor battery and ESC Using the 25 Amp Pro Brushless Controller This controller is very simple to use and for safety will not arm the motor until the throttle stick has been held in the Idle Off position for more than 1 second The controller will indicate the soft cut off voltage setting every time you plug the battery in by first emitting a low long tone to show startup You will then hear 2 for 2 cell Li Po or 3 for 3 cell Li Po medium length mid tones to indicate the cell count or 7 beeps if 70 Smart Cut is selected helping you to confirm the setting before every flight Connecting the ESC to the Motor The three wires from your motor connect to the three female gold bullet connectors on the ESC The order of connection to the motor is not important you can plug any motor wire into any connector If when you test the system the motor runs backwards you can simply unplug and sw
