8.5 kHz (fixed)
battery voltage x 0.67
Designed for medium-sized, high-performance airplanes
Works with outrunner and inner-rotating brushless motors
25A continuous current, 28A surge currents
2A BEC circuit
Very simple to use, with on/off brake and safe-start
The Silver Series speed controls for brushless motors are compatible with NiCd, NiMH and Li-Po type battery packs. The feature pre-installed Deans battery connectors and gold-plated bullet plugs for motor connections. In addition, they come pre-wired with universal radio connectors.
These speed controllers are so advanced that they require no setup! They automatically detect battery type and input voltage at hookup. This sets the low-voltage cutoff automatically.
There may be an incompatibility issue using ElectriFly Silver Series brushless ESC's with some AXI brushless motors.
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 male star 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 230°F 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, HCAM4020 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: 230°F (110°C) Timing Angle: 12° Brake: ON/OFF COMMENTS: To use with "Old Airtronics" Rx, requires adapter. **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 advancedabove 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 thepower 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 todisconnect the battery from the speed control!
