Do not fly under the conditions below
Wind strong enough to make the trees rustle
A street with many trees or street lamps
Close to high voltage electrical wires
High Population density areas
Cautions for flying
front lawns and parks make excellent flying areas. Make sure you
have permission to fly and follow safety guidelines set by local
authorities. The calmer the wind, the better!
Note for Storage
Please disconnect the lipo packs when finished flying
Do not press or crush the airplane when storing
The best way to store is to hang the airplane to keep the control
surface rigid

Glue the motor mount as shown .Use CA glue
Insert motor mount into the fuselage .use CA glue.
Screw motor into the motor mount , using 4pcs screws.
Cut opening for ESC .insert ESC into opening –the hole must be
about 1mm smaller,The fuselage foam will hold the ESC in the right
position.
Using sharp knife cut an opening for rudder and elevator servos
and for receiver .
The opening for servos must be 1mm smaller from each side .

Insert the servos into the hole as shown .use CA glue .
Install the pushrod connector to the servo arm, insert the quick lock
onto the pushrod connector .
Use your radio system and determine which hole in the servo arms
will give the desired control throw. Install the servo arms on the
servos.
Into the fuselage drill 8mm deep slot for servo cable of the ESC
.Install the servo cable into this slot for receiver.
Using sharp knife cut the slot for the tube at left side of the fuselage
.the slot must be 3mm deep .position slot as shown.

Press the tube into the slot in fuselage as shown .glue it using CA
glue .
Install the other end of the Z wire (elevator pushrod) to the elevator
servo arm．
Install the other end of the Z wire (rudder pushrod) to the rudder servo
arm

Using sharp knife cut an opening for ailerons servo .The opening
must be 1mm smaller from each side.

Into the fuselage drill the 8mm hole for aileron servo cable up to
the space for receiver.
Glue the extension of the servo arm onto the ailerons servo arm
using CA glue.
Before gluing rough the arm and extension.
Insert connectors into extension of the servo horn .
Insert the ailerons servo into the hole and put through the servo
cable into the opening for receiver .glue the servo using fusion
glue.
Using sharp knife cut an opening for ailerons servo horn.
Switch on the RC-set for to have the servo in neutral .install the
servo horn on the servo.

FinalCheck
Checkthe model.Itmustbesymmetrical andnot twisted.
Radiocontrol setinstallation
review top and side view, showing a basic radio installation. Put accu
pack in fuselage as shown. Accu pack will be used for balancing the
P51D. Use instruction guidefor speed controllerfor operating with electro
powerset.
Centre of gravity
Support your model with your fingertips. It should balance, slightly nose
down, when your finger tips are 45-55mm behind the leading edge of the
wing. Move the battery to balance your modell properly. Do not try to fly
anout-of balancedmodel, asitwillcrash!
Flying
Check each control surface for the correct movement and adjust
pushrods. Checking running of the motor. For taking of you need a flying
fieldabout 100m longwithout treesaround. Holdyour modelon the hand ,
put ¡±full gas¡±.Throw the model in the air little bit nose up .Move elevator a
