Warning! High power motor systems can be very dangerous! High currents can
heat wires and batteries, causing fires and burning skin. Follow the wiring directions
carefully! Model helicopters equipped with high power motors can kill. Always fly at a
sanctioned field. Never fly over or near spectators. Even though this controller is
equipped with a safety arming program, you should still use caution when connecting the
ib
1.0 Features of the Pegasus-35H™:
•Microprocessor controlled
•Low Resistance (.0011 ohms)
•High rate (2800 Hz) switching (PWM)
•Up to 35 Amps continuous current (with proper air
flow)
•Battery Eliminator Circuit (BEC) provides power
to receiver and servos - eliminates separate receiver
battery
•Audible arming signal alerts when system is armed
•Six to eight cells with three standard micro servos
and gyro
•Six to eight cells with two high-torque micro servos
and gyro
•Up to ten cells with two standard micro servos and
gyro
•Eighteen cells MAX with BEC disabled.
•Safe “power on” arming program ensures motor
will not accidentally turn on
•Low torque “soft start” prevents damage to fragile
gearboxes
•Auto shut down when signal is lost or radio
interference becomes severe
•Rugged surface mount construction
2.0 Wiring Your Pegasus-35H™:
Tools required:
Wire cutters Wire strippers (optional)
Soldering Iron (25-40 watts - Do not use a soldering “gun”)
Parts required:
Solder (rosin core “electronic” solder - do not use acid core “plumbers” solder)
Battery connector
2.1 Adding the Battery Connector
The battery connector is attached to the left side of the controller (looking down at the heat sink/label).
Cut the wires to the length you require on the battery side. Strip off of the wire insulation to expose just
enough wire to attach the battery connector. (Note: if you do not have a pair of wire strippers, you can
use a modeling knife to carefully cut through the insulation around the wire. Then the insulation should
easily pull off the wire.) Attach the battery connector to the wires ENSURING THAT THE POLARITY
(red wire to battery red wire, black wire to battery black wire) IS CORRECT, following the instructions
for the battery connector.
2.2 Attaching the Motor Leads
The motor is connected to the right side of the controller (looking down at the heat sink/label). Cut the
wires to the length you require on the motor side. Strip the wire insulation to expose just enough wire to
solder the wires to the motor terminals. (Note: If you do not have a pair of wire strippers, you can use a
modeling knife to carefully cut through the insulation around the wire. Then the insulation should easily
pull off the wire). There should be a ‘+’ symbol or a RED DOT on the end of your motor which
indicates which terminal must be connected to the RED wire. Connect the other terminal to the white
wire. A fuse (30-45 amps) may be connected inline in either the black or red power wire. A fuse is
recommended for the safest operation. DO NOT PLACE A FUSE IN THE CIRCUIT BETWEEN
THE BATTERY AND SPEED CONTROL. YOU COULD LOSE CONTROL OF THE MODEL.
Align the wires carefully and solder to the motor terminals. Ensure that all connections (battery and
motor) are correctly polarized.
IMPORTANT NOTE: YOU MUST BE SURE THAT ALL CONNECTIONS ARE CORRECT WHEN
CONNECTING THE SPEED CONTROL. Incorrectly connecting the speed control could cause
permanent damage to the controller.

2.3 Connecting the Receiver
Connect the receiver lead (the three color, twisted wires with a connector on the end) to the throttle
channel on your receiver (usually channel 3). Do not connect a battery to the receiver, as the Pegasus-
35H™will supply power to the receiver and servos through the receiver connector. If you are using
more than ten cells, you will need to use a separate receiver battery. See the section 4.0 (under the
heading BEC) for instructions on disabling the BEC to use a separate receiver battery.
ALWAYS PERFORM A RANGE CHECK BEFORE FLYING WITH ANY NEW SPEED
CONTROL! PERFORM YOUR RANGE CHECK AT FULL THROTTLE, HALF THROTTLE
AND NO THROTTLE.

3.0 Flying with Your Pegasus-35H™:
Initialization sequence:
1. Connect the speed controller receiver connector to the proper channel on your receiver (usually
channel 3)
2. Turn on your transmitter.
3. Connect the main power battery to the speed controller. A single “beep” will be emitted.
4. The speed controller will remain unarmed (will not operate) until it sees more than four seconds of
“OFF” throttle. Move the throttle arm to the lowest position on your transmitter, wait at least four
seconds. Two “beeps” will sound alerting that system is armed. Test the controller to make sure that
the throttle operates.
5. Go fly!
4.0 Using the Features of Your Pegasus-35H™
BEC - The BEC power is supplied to the receiver and servos through the receiver connector wires. If
you wish to disable the BEC and use a separate receiver battery (required for the use of more than ten
cells), you must first cut the red wire in the trio of receiver wires. Simply use a pair of wire cutters to
remove a short section of the red wire near the receiver connector, and be sure to insulate the cut wire
with a bit of electrical tape. Then you may safely use a battery with your receiver.
Loss of Transmitter Signal, or excessive radio noise cutoff - Motor cutoff will also occur if the signal
from the transmitter is lost, or if the radio noise becomes excessive. After radio connection has be
reestablished, the motor can be restarted by moving the throttle to the braking position (full off) for four
seconds.
Safe Power Up - The Safe Power up feature is a “finger saver”, designed to prevent the motor from
starting accidentally on power up. To arm the controller, the transmitter stick must be held in the “OFF”
position (all the way down) for at least four seconds. Until the controller is armed, it will not provide
any power to the motor, regardless of where the throttle stick on your transmitter is positioned. Before
flying your model, be sure to “blip” the throttle to ensure that the controller is armed.
5.0 Troubleshooting
Everything is hooked up correctly, the BEC (receiver and servos) works, but the throttle does not
work.
The controller is not seeing the four seconds of “dead space” (low throttle) and is not arming. Try
moving your throttle stick all the way down, and moving the trim all the way down. Wait for four
seconds and try the throttle again. If it still does not arm, you may need to reverse the throttle control on
your transmitter (see your radio documentation). You may also check to make sure that your endpoint
adjustments on your radio (if it has them) are set all the way open.
Nothing seems to work, receiver and servos are dead, and the throttle is dead.
Check all connections to ensure that they are correct, and that the polarity (+/-) connections are correct.
Ensure that the battery is not connected to the motor side of the speed controller. If everything is
correctly connected, and the receiver and servos still do not work, contact the dealer where you
purchased your Pegasus-35H™or contact
Castle Creations™ directly. (see info below)
