Mini High Power
Electronic Speed Controls w/BEC
INTRODUCING THE ELECTRIFLY C-20 AND C-30
The ElectriFly C-20 High frequency and C-30 High Power ESCs feature the
"Safe Start" system to prevent accidental motor starts by disabling the motor
circuitry until the throttle stick is moved to full throttle, then to the "off"
position.
Other features include BEC circuitry which allows the motor battery to power
the receiver and servos. When the motor battery voltage is reduced to 4.8
volts, the low voltage cut-off circuitry stops the motor while continuing to
supply power to the receiver and servos. This eliminates the need for and
weight of a separate receiver battery. Both speed controls come with thermal
shutdown protection that turns the motor off if the transistors overheat.

IMPORTANT PRECAUTIONS
Read and follow these instructions carefully before using.
GDo not operate the airplane on or near water. Never allow water, moisture
or any foreign material onto the ESC's PC board.
GNever use more cells then specified for the main battery pack.
GThe ceramic capacitors must be properly installed on the motor to prevent
radio interference.
GAlways disconnect the motor battery from the ESC when not in use.
GAlways switch on the transmitter before switching on the ESC.
GUse heat shrink tubing to insulate any bare wires from the motor battery
to the ESC and from the ESC to the motor to prevent a short circuit.
GAllow the ESC to cool before touching.
STEP 1 THE RECEIVER PLUG
The receiver plug attached to the speed control plugs
directly into a Futaba "J" receiver. However, if you are
using an Airtronics "Z", Hitec "S" or JR receiver, you will
need to slightly modify the receiver plug on the ESC. To
modify the plug, use a hobby knife or wire cutter to
carefully cut off the alignment tab on the side of the
receiver plug as shown.
The white "signal wire" on the ESC receiver plug should be in the same
position in the receiver slot as the white wire on Futaba, the blue wire on the
new Airtronics "Z" connector, the yellow wire on the Hitec "S" connector or the
orange wire on the JR connector. WARNING: This connector is NOT directly
compatible with the old Airtronics connector style. Use an Airtronics Servo
Adapter to connect this ESC to the older style Airtronics radios.

STEP 2 MOUNTING THE SPEED CONTROL
Determine the best location for the ESC inside the fuselage. The ESC should
be in a position which allows good airflow for proper cooling, and closely
enough to the motor so the motor wires reach the motor. It is highly
recommended to put cooling air intake holes in the front of the fuselage and
exit holes towards the aft end.
The best method to mount the ESC in the fuselage is with Velcro
will be mounted on wood, first saturate the wood with thin CA and allow to
dry. Cut a piece of Velcro (both hook and loop) approximately 1/2" x 1". Attach
the hook (hard) material to the inside of the fuselage. Clean the bottom of the
ESC (the side with the wires) with rubbing alcohol and attach the loop (soft)
material. The ESC on/off switch can be mounted on the outside of the fuse
using two #2 x 3/8" self-tapping screws.
STEP 3 INSTALL THE MOTOR CAPACITORS
Motors generate radio noise which can interfere with your receiver and cause
problems. Your ESC includes two .10 F (104) and one .047 F (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.
GCut a piece of heat shrink tubing long enough to cover one of the leads on
both of the .10 F capacitors, leaving approximately 1/4" of the lead exposed
at the bottom.
GSolder the 1/4" of exposed lead from one of the capacitors to the positive
brush terminal on the motor end cap.
GSolder the 1/4" of exposed lead from the second capacitor to the negative
brush terminal on the motor end cap.
G Solder the remaining leads from both capacitors to the side of the motor case.
GCut two pieces of heat shrink tubing long enough to cover both leads on the
.047 F capacitor, leaving approximately 1/4" of the lead exposed at the
bottom.
GSolder one of the leads to the positive brush terminal and the other lead to
the negative brush terminal.
GSolder the positive (+) lead from the ESC to the positive brush terminal on
the motor and the negative (-) lead to the negative brush terminal on
the motor.
SCHOTTKY DIODE
Installing the schottky diode will provide a slight increase in the ESC
efficiency and reduce its operating temperature. The schottky diode must be
installed correctly. Installing it backwards will destroy it.
Correct Installation Of The Schottky Diode:
GSolder the lead closest to the silver band on the diode body to the positive
(+) terminal on the motor.
GSolder the lead opposite the silver band to the negative (-) terminal on
the motor.
STEP 4 CHANGING THE MOTOR & BATTERY
Because of the many different types of plugs available, we cannot cover the
installation of each plug type. The following instructions will help you prepare
the wires for installation of any plug type.
1. Remove the existing plug by cutting the wires behind the plug, and
separate the red and black wires.
2. Strip 1/4" of insulation from the end of the red wire.
3. Twist the strands of the bare wires together tightly.
4. Tin the ends of the wires with solder made specifically for soldering
electronics. We recommend 60/40 rosin core solder.
A. Pre-heat your 15 to 30 watt soldering iron.
B. While holding the tip of the soldering iron on the bare wire, touch the
solder to the bare wire very near the iron tip and allow the liquid solder
to flow through the wire. This whole process should only take a couple
of seconds. Make sure the soldering iron is not held on the bare wire too
long, otherwise the insulation will start to shrink.
C. When properly tinned, the end of the wires should be completely covered
with a light coat of solder.
