**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.
