This is the ElectriFly Silver Series 45amp brushless electronic speed control. Great for larger high performance airplanes. Delivering 45A of continuous current with a built-in Battery Circuit which can handle 2A, this ESC is simple to use and very affordable.
Requires: Mating motor and battery connector
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 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!
