EZX-R, EZX-R Pro Installation and Set-up Instructions

REVERSING

SPEED CONTROL

Congratulations on your purchase of the EZX-R, EZX-R Pro high frequency
reversing electronic speed control. The EZX-R, EZX-R Pro represents the latest
technology for high performance and reliability in a reversing type ESC. Set it for
two-way control for fun or forward only for racing/

the EZX-R, EZX-R Pro does it all!

Step 1. Mounting instructions:

1.) Mounting the EZX-R, EZX-R Pro should be done with double-sided tape in a
location with good airflow that does not interfere with the suspension of the vehicle.

Refer to your cars instruction manual for their suggested location

Step 2. Hook up Instructions:

1.) Connect the receiver lead to the throttle channel of the receiver.

This is typically CH#2. (Caution: The plug supplied will work with
Hitec, Futaba, JR and Airtronics "Z" only)

2.) Connect the ESC's blue (-) and Yellow (+) wires to the

motor via the b ullet connector C's Tamiya type connector to the battery.
(Note: If you choose to use a different type connector you will have to
change the stock connector to match.)

4.) Note: Always make sure you have three 0.1uf capacitors on the motor.

One from the positive motor tab to the ground (Case), the second from the
negative motor tab to the ground and the third from the positive motor tab to
the negative motor tab.

5.) Warning: Do not use a Schottky diode if using the reverse mode;

it may damage the speed control.

Step 3. Set-Up Instructions:

Two-Way Setup (Reversing)

1.) Turn on TX and make sure the EPA's or ATV's (If you have them) are set to 100%
and the trim is at neutral.

2.) Turn on the ESC switch while pushing the set-up button then let off.

3.) The ESC light will then flash once. (The neutral point of throttle is set.)

4.) Immediately pull full throttle, the ESC light will flash once again.
(Full power point of throttle is set.) Note: Motor will not run during the set up
procedure even if connected to the ESC.

5.) Immediately push full brake; the ESC light will flash once.
(Brake and Reverse is set.)

6.) Return the throttle to neutral; the light will flash twice. (All setting was properly done)

7.) Continuous flashing means there was an error. Repeat the set up procedure.

One way Setup (Forward Only)

1.) Turn on TX and make sure the EPA's (If you have them) are set to 100%

2.) Turn on the ESC switch while pushing the set-up button then let off.

3.) The ESC light will flash once. (The neutral point of throttle is set.)

4.) Immediately pull full throttle, the ESC light will flash once again.
(Full power point of throttle is set.) Note: Motor will not run during the set up

procedure even if connected to the ESC.

5.) Immediately push full brake; the ESC light will flash once. (Brake is set.)

6.) Immediately push the ESC set-up switch while pushing full brake;
it will then flash twice. (All set)

7.) Continuous flashing means there was an error. Repeat the set up procedure.

Precaution

1.) Never get your electronics wet.

2.) Always use the supplied heat sinks. Failure to do so will overheat your ESC and
will void the warranty.

3.) Never use less than 7.2V (6 Cell) or more than 8.4V (7 Cell).

4.) Always use three 0.1uf capacitors on the motor.

5.) Never use a Schottky diode when using the reverse function.

6.) Motor limits are calculated and must correspond with the proper gearing.
Over gearing will cause the ESC to overheat. If this happens use a smaller
pinion (motor) gear.

7.) Always make sure your batteries and connectors are wired properly.
Red is positive (+), and black is negative (-). Reversed polarity will damage the ESC.

8.) Always turn your transmitter on first and off last.

9.) Always disconnect the battery from the ESC when not in use.

10.) Always insolate any exposed wires.
