INSTALL THE MOTOR CAPACITORS
Motors generate radio noise which can interfere with your receiver and cause problems. Your ESC includes
two 100µF (104) and one 47µF (473) non-polarized, ceramic capacitors. These capacitors must be used at
all times, and on every motor to help reduce the radio noise generated by the motor and prevent possible
damage to the ESC.
A. Cut a piece of heat shrink tubing long enough to cover one of the leads on both of the 100µF capacitors,
leaving approximately 1/4" of the lead exposed at the bottom.
B. Solder one exposed capacitor lead to the positive (+) brush terminal on the motor.
C. Solder one exposed lead on the second capacitor to the negative (-) brush terminal on the motor.
D. Solder the remaining leads from both capacitors to the metal side of the motor case.
E. Cut two pieces of heat shrink tubing long enough to cover both leads on the 47µF capacitor, leaving
approximately 1/4" of the lead exposed at the bottom.
F. Solder one lead to the positive brush terminal, and the other lead to the negative brush terminal.
G. Connect the positive (red) lead from the ESC to the positive brush terminal on the motor and the negative
(black) lead to the negative brush terminal.
SCHOTTKY DIODE
Installing the schottky diode will provide a slight increase in the ESC efficiency and reduce its operating
temperature. To avoid damage to the diode, it must be installed correctly, as follows:
A. Solder the lead closest to the silver band on the diode body to the positive (+) terminal on the motor.
B. Solder the lead opposite the silver band to the negative (-) terminal on the motor.
TRANSMITTER ADJUSTMENTS
Adjusting the transmitter is critical for proper ESC operation. The transmitter throttle adjustments should be
set as follows:
1. Set the transmitter’s throttle travel adjustment, ATV, EPA or ATL to maximum.
2. Set the throttle trim and sub-trim to neutral or zero.
3. Set the throttle reversing switch to reverse.
RECEIVER OPERATION
(Show pic of receiver, call out channels, antenna, etc.)
A. Connect servos and input battery pack as shown above.
B. Turn "ON" the power switch on the Tx, then the power switch on the Rx. Make sure all servos operate
in the proper directions according to the movement of the Tx stick. When the Tx stick is at center
position, the servo horn should be perpendicular to the servo itself. When connected to the airplane's
control surface, it should be at neutral position when the stick is at center. If neutral position of the
control surface has been changed, even though the stick is still at center, change the length of the pushrod
by adjusting the clevice on the end of the rod. Make sure each control surface is set per the instructions
of your airplane.
C. Turn off the system, receiver first, then transmitter.
D. Wrapping the Rx in foam rubber (HCAQ1000 or HCAQ1050) can greatly help protect the Rx from
excess vibration. Covering the Rx with a plastic bag can also help prevent excess moisture from
penetrating the Rx and damaging the circuitry.
E. Install the Rx into the model as shown in the model's instruction manual. Do not cut or bundle the Rx
antenna in any way. It is important the antenna is extended to its maximum length before use so to
maximize operational distance, or "range". It's also helpful to route the antenna as far away from servo
and battery leads as possible, to help prevent interception of unwanted stray signals. For most aircraft,
the antennas are routed down the tail.
F. Range test the radio system prior to flight. Because electric motors generate electrical noise it is critical
to range test the airplane with the motor on. With the transmitter antenna collapsed and a helper holding
the airplane, operate the flight controls while walking away from the airplane. Acceptable range should
