TAIL WHEEL AND ELEVATOR GUIDE WIRES INSTALLATION: With the model still upside down, draw the centre line of the section where the carbon tail wheel unit will be located, and then mark the location where you need to drill the holes for the bolts that will hold the tail wheel in place.

AILERON SERVO INSTALLATION: Locate and cut the covering where the servo will be installed. We recommend cutting only the diameter of the main part of the servo. Allow the servo to sit on top of some Oracover, thus trapping and securing the Oracover in place.
RUDDER SERVO INSTALLATION: Screw the rudder servo to the allocated tray inside the fuselage Centre the servo with your transmitter and attach the double servo arm Attach the provided pull pull wires to the rudder control horns and thread the pull pull wire carefully through the fuselage slots all the way back to the actual rudder servo.
ELEVATOR SERVO INSTALLATION: Locate and cut the covering where the servo will be installed, at the rear of the fuselage, just under the elevator. Attach your required extension lead to the servo, allowing sufficient length for the lead to reach your receiver or Powerbox without needing further extensions.
MOTOR INSTALLATION: The Pitts is provided with the firewall pre-mounted at the factory, laser marked where the centre-line is, ready for you to simply square your engine to it. The engine box come with the appropriate engine incidences applied, so all you need to do is make sure that this any standoffs are all the same size to assure a correct engine incidence.
THROTTLE SERVO: For the installation of the throttle servo, simply screw the servo to the provided servo mount, and then screw and glue this in its final location where required for your particular engine. Use the included pushrod to connect to your engine, making sure that of a smooth and bind free movement.
COWLING INSTALLATION: The cowling is installed with a single pre-installed bolt on the top half, from the inside of the fuselage going forwards, and two additional bolts going through the cowling from the bottom. With the cowl off, turn the model over, and place some small strips of masking tape in line with the two bolt holes.

INSTALLATION OF ANCILLARY COMPONENTS: Check the correct location of your chosen battery and ancillary components depending on your CG. Install your receiver with double sided tape or velcro, making sure that all servo leads can be easily connected without being too tight, and that the receiver is securely fixed in place. For specific tips on receiver and antenna location, please consult your receivers manual.

Note that the two laser cut holes are for the fuel and smoke tank vents...
Page 62
WHEELS PANTS INSTALLATION: Slide the wheel pants over the wheels and axles, supporting the rear of the pants to line up with the ground and mark where to drill the two screw holes in the wheel pants. Remove the wheel pants and drill the holes for the appropriate holes. Before putting back on the plane, mount the bolt with the blind nut on the wheel pant and tighten until the nut sits flush with the wheel pant.

ELEVATOR GUIDE WIRES The guide wires are important as they add extra strength to both the elevators and the main wings. The elevator has guide wires both top and bottom. The bottom guide wires are fixed to the fuselage via the cross member installed previously (during the tail wheel step).
WING STRUTS The wing struts must be installed in the correct order and location in order to assure the correct wing angle and incidences. To make setup simple, inside the struts you will find laser engraved descriptions of where each side of the wing strut should be attached.
Page 73
WING GUIDE WIRES The wing guide wires are fitted with a quick release on one end, and are permanently fixed at the other. The support that we installed earlier under the landing gear is where the guide wires will be permanently attached, using the same crimping method described previously.
Page 77
BALANCING THE CG OF AIRPLANE: The CG is marked on the central fuselage wing support. Thread wire through the indicated CG hole, then proceed to setup the model fully and then lift using said wire. The model should sit level when lifted. Personal CG preference can then be adjusted following the first flight.
CONTROL THROW DEFLECTIONS AND SUGGESTED EXPO. General flying: Surface Deflection Expo Ailerons: 20º Elevators: 20º Rudder: 20º Full 3D acrobatics: Surface Deflection Expo Ailerons: 40º Elevators: 40º Rudder: 45º FIELD SETUP: Setup at the field can be done very quickly. The correct procedure for setup should be as follows:...
Page 81
0- The main “A” frame is permanently mounted to the fuselage 1- Insert the lower wing and secure to the fuselage, along with the servo connections 2- Secure the struts to the lower wing, along with the servo connection. This is done by simply sliding the quick release plate under the screws and tightening.
Page 84
6- Secure the elevator tension wires as per picture below: All this can be done in just a few minutes:...
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 SUCCESFUL MAIDEN AND MANY HAPPY FLIGHTS WITH YOUR NEW MODEL.
