We suggested use PilotRC
Brake controller for your
Predator, it can provide
independent brake voltage,
more powerful and reliable.

Note: The brake controller
support power is 7.4V-25.2,
we suggest use 11.1V for
support power.

Landing gear assembly - nose

1: Install the servo to the nose landing gear.

2: Install the servo arm and the push rod. Adjust it to make sure the plane can go
straight approx. You still can adjust by radio after install it.

3.Double check the positioning of
your gear before drilling any holes.
Make sure that the gear movement
is free of any obstacles.

4.Remove the gear and carefully drill
the holes to accept your chosen
screws. We recommend the use of
bolts and blind nuts, however wood
screws can also be used as a “failure
point” in case of a hard landing.

Wing Servo/Flaps Assembly

The control horns are pre-installed at the
factory, ready for use.

Elevator/ Rudder Assembly

To assemble the rudder, insert the aluminum tube

Next connect all the servo wire and insert the elevator to the mounting hole

Fasten all of the screws, and make sure they are tighted enough.

Elevator/ Rudder Assembly

Connect all the servo wire and insert the rudder tube into the
mounting hole on the fuselage.

Fasten all of the screws, and make sure they are tighted enough.

Fuselage Assembly

The 126” Predator’s fuselage divided three pieces. Rear section easily
removable for transport

Fuselage divided three parts:
Front part (For front landing gear, electronic device)
Middle part（For tank, engine, wings）
Behind part（For exhaust pipe, rudder, elevator）

Fuselage Assembly

Front – Middle part

1.First, put the front fuselage and middle fuselage on table or support
shelf. And make sure front-middle part can connect through the limit hole.

2.When connected, use the head screws to fasten all of it. and make sure
all of screws are tight.

Fuselage Assembly

1.When you finish the front-middle part. Then connect the middle-behind
part like before.

Middle - Behind part

2.Use the butterfly screws to fasten all of it, and make sure all of screws
are keep tight.

Circuit Arrangement

Because the Predator fuselage divide three part. and each part have
many electric parts need assemble, so there is many circuit…… So for
easy arrange the circuit, these pictures showed how the circuit arrange in
the fuselage.

For circuit arrange easily, we set the circuit arrangement tube in each
fuselage, it’s under the mounting plate or at fuselage’s left/right side.

Circuit Arrangement

The front part circuit arrangement(electric parts ect……)

The middle part circuit arrangement(wings, gear)

Circuit Arrangement

The behind part 3 in 1 connector circuit arrangement (rudder, elevator)

All these pictures are suggestion, you can arrange circuit by your way.

And for easy arrange these circuit, you may need some tools like
tweezers, stay wire ect…

Electric parts Arrangement

The electric

we divided it
for two parts:
front part is oil
filler（smoke

and
MERCURY
display, switch.
behind part is
MERCURY,
landing gear
controller, oil

pump,

receiver, flying
control system.
ect……

Engine Arrangement

For install the engine, we suggest install the exhaust nozzle first, when
the nozzle setting done, we can locate the engine’s setting position, and
install it.

Side support

Need 4
tapping
screws to
fasten it.

Here use M3
claw screws
to fastening it.

Engine Arrangement

When arrange the engine, must make sure the screws are tight with
engine and mounting plate

Tank Arrangement

The 126” predator use PilotRC 3 in 1 Kevlar tank. It’s included
7800ml fuel tank, 2400ml smoke tank and 500ml UAT

Tank Arrangement

To make sure the tank arrange position, put the tank in to the slot,
and make sure the tank is in the current position.

When tank in position, use double sticky tape to stick the tank on the fuselage,
and use the velcro strap to hold the tank, make sure the tank is tight with
mounting plate.

This tank limits plate you need install
by yourself, use glue to glue it on the
fuselage, and use bolt to securing it.

Tank Arrangement

After the tank arrangement, to set the fuel vent installing
hole in the fuselage, it’s under the mounting plate, behind
the air inter.

CG Checking

The Predator have CG measuring tools for checking CG, you can
checking CG by this tool.

Please check the CG
without empty oil tank.

Flying Setting

■ Make sure you have the right model programmed into your transmitter

■ Check the direction of each surface not and also right before you take off .

■ Remember nothing wrong on the ground ever improves in the air

■ Check the air plane with the engine running and do a range check with

■ your body between you and the plane at least 150 feet.

■ Check your battery voltage after each flight, in case one servo is draining your

battery

■ Recheck all screws ,horns and linkages for slop after your maiden fight and
check for damage if you made a bad landing you first time

■ Have an experienced pilot fly it for you the first time if you have any doubts in
your mind about the maiden flight

■ Take a break after you first flight and let the adrenaline burned off by bragging to
your fellow members how good it flies

■ Fly low and at a medium speed on your first few flight

■ Listen to your engine run and have an observer with you to remember what you

talked about during the flight or if you get into trouble . Always balance your props,

Flight Preparation

vibration is a killer.

■ Remember nose heavy airplanes fly all the time, tail heavy airplanes fly only
once. Be on the CG!

■ Flying two mistakes: high in the beginning and not close to people, planes or
runways. Being a center of the runway hog does not endear you to many modelers.

Double Check

Double check that all screws are installed, all components tightly secured, batteries
and or fuel tank are full, all surfaces are working in the correct directions, balance is

correct and range test passed before performing your maiden flight.

WE WISH YOU A SUCCESSFUL MAIDEN AND MANY HAPPY FLIGHTS WITH YOUR NEW
