Tech Notes
 
NOTES FROM OUR TECH DEPARTMENT
This is the ElectriFly Silver Series 25 amp Brushless Electronic Speed Control.
             Great for medium sized, high performance airplanes.
            Delivering 25A of continuous current with a built-in
            Battery Eliminator Circuit which can handle 2A, this
               ESC is very simple to use and very affordable.

FEATURES: Compatible with NiCd, NiMH and LiPo batteries Auto-detects input volts and sets Low-Voltage cutoff 8.5kHz switching frequency, for good run-time and cool operation Pre-installed Universal radio connector* (see Comments below) Pre-installed WS Deans Ultra male connector for battery (see comments below) Pre-installed gold plated 3.5mm female bullet connectors for motor High powered switching BEC (Battery Eliminator Circuit) which handles 3 or 4 standard servos Full proportional forward and smooth throttle response with ON/OFF brake Safe Start System** (see details in Comments below) Thermal Protection stops motor when maximum temperature 230F is reached 180 Day Warranty (USA & Canada Only)

INCLUDES: One Brushless ElectriFly Silver Series 25A Speed Control with pre-installed receiver connector, battery connector, and motor connectors.

REQUIRES: Mating motor connectors, GPMM3112 Mating battery connector, WSDM3000

SPECS: Length: 1.58" (40mm) Width: 1.02" (26mm) Height: .31" (8mm) Weight: .92oz (26g) Input Voltage: 7-12 cells NiCd/NiMH 3-4 cells LiPo (20V input w/o BEC) Output Current: 25A continuous maximum 28A surge maximum Max Output Power: 250 watts ON-resistance: .15 ohms Operating frequency: 8.5kHz BEC: 5V/2A Low Voltage Cutoff: Battery voltage x .67 Thermal Cutoff: 230F (110C) Timing Angle: 12 Brake: ON/OFF

COMMENTS: To use with "Old Airtronics" Rx, requires adapter: AIRM4400 **Safe Start System: Move throttle stick to full throttle position, then to "OFF" position, then slowly advance throttle and motor will begin to run.

The "Silver Series" line of brushless electronic speed controls include many built-in safety features. One such feature COULD POSSIBLY CAUSE THE BRUSHLESS MOTOR TO STOP ROTATING when the transmitter's stick is at an extremely low position and/or if rotation of the brushless motor is impeded or obstructed in some way. This is NORMAL, as the ESC is detecting that a problem possibly exists with the motor and/or speed control. Rotation of the motor is stopped to protect the speed control from possible damage. WARNING!! If the ESC and motor have already been armed and the motor has been rotating normally, yet after moving the throttle stick to near minimum the motor suddenly ceases to rotate normally even if the throttle stick is advanced above minimum throttle, DO NOT PLACE YOUR HANDS NEAR THE PROPELLER!! FAILURE TO OBEY THIS WARNING COULD RESULT IN PERSONAL INJURY!! From this point, moving the throttle stick up - even to full throttle might not cause the motor to rotate BUT THE MOTOR IS STILL ARMED AND ACTIVE DURING THIS TIME!! To regain control of the motor, move the throttle stick to absolute minimum throttle position and then advance the throttle stick upwards once again. Alternatively, you can disconnect the battery from the ESC, then re-connect the power source and re-arm the system. NEVER get near the propeller if the speed control is connected to input power! ALWAYS make sure the throttle stick is at minimum position before attempting to disconnect the battery from the speed control! ElectriFly is not responsible for incidental damage or personal injury as a result of misuse of this product.
