3- Assembly
Main landing gear assembly:
Screw the wheel axles on to the landing gear, and then slide on the wheels and secure in place with the provided grub screws.
Position the fuselage upside down and screw on the carbon undercarriage to the fuselage using the nuts and bolts provided.
Some users may prefer to leave the wheels until the end of the build, to prevent the model moving on the build table.
Tail wheel installation:
With the model still upside down, position the carbon tail wheel unit on its correct location and mark on the underside of the fuselage to drill the holes for the screws that will hold the tail wheel in place.
Attach the ball link to the underside of the rudder using a small amount of Epoxy.
Run the control rod through the above ball link and screw the tail wheel unit to the fuselage using the wood screws provided.
We recommend to keep the pivot point of the tail wheel as in line with the hinge line as possible to assure a bind free movement of the springs.
STABILISER installation:
Cut free the trailing edge of the vertical rudder in line with the stabiliser, in order to allow you to slide the stabiliser into the fuselage. Keep the removed section for later.
Trial fit the stabiliser into the fuselage. Make sure that it is centered (measure the tip of the stabiliser to the tip of the wing on both sides and make sure they are the same distance) and correctly aligned (looking at wings and stabiliser, should show all being parallel)
Once centred and aligned, mark where it meets the fuselage. Remove the stabiliser and carefully cut the covering on the inside of your mark, for gluing.
Prepare a mix of Epoxy and generously coat the inside of the fuselage where the stabiliser will fit, then re-insert the stabiliser into its final location, checking again that it is centred and aligned.
Glue back into place the section removed earlier in this process.
Excess epoxy glue can be removed with acetone
Installing the servo horn on the elevator:
It is very important to sand horn to assure a strong bond once glued to the model.
Locate and cut the covering where the horns will be glued
Glue them to the surface using epoxy glue
Excess epoxy glue can be removed with acetone
Installing the servo horn on the rudder:
It is very important to sand horn to assure a strong bond once glued to the model.
Locate and cut the covering where the horns will be glued
Glue them to the surface using epoxy glue
Excess epoxy glue can be removed with acetone
Installing the servo horn on the ailerons:
It is very important to sand horn to assure a strong bond once glued to the model.
Locate and cut the covering where the horns will be glued
Glue them to the surface using epoxy glue
Excess epoxy glue can be removed with acetone
Aileron servo installation:
Install and glue the included hinges.
Locate and cut the covering where the servos will be installed.
Route the servo wire through the wing and screw the servo in place.
Centre the servo with your transmitter, attach the servo arm and connect the servo to the ailerons with the pushrods provided.
Rudder servo installation:
Install and glue the included hinges.
Locate and cut the covering where the servo will be installed, at the rear of the fuselage, under the elevator.
Route the servo wire through the wing and screw the servo in place.
Centre the servo with your transmitter, attach the servo arm and connect the servo to the ailerons with the pushrods provided.
ELEVATOR servo installation:
Install and glue the included hinges.
Locate and cut the covering where the servo will be installed, at the rear of the fuselage, under the elevator.
Route the servo wire through the wing and screw the servo in place.
Centre the servo with your transmitter, attach the servo arm and connect the servo to the ailerons with the pushrods provided.
MOTOR installation:
Place the cowl on the model and measure the gap between the firewall and motor hub/spinner position.
Follow the laser diagram on the firewall to drill the necessary holes for the motor. These are designed for use with the Pilot-RC CC15 motor. If using a different motor, hole position may vary.
Check if your engine requires any standoffs or washers in order to reach the necessary position, before attaching permanently to the model using bolts and blind nuts as per the images.
Secure your ESC to the firewall close to the motor, ideally in a location that will allow airflow over the ESC to aid in its cooling.
Cowling installation:
The cowling is installed using four screws that go into four “tabs” in the fuselage.
The exact location of the cowling can be adjusted slightly to allow an easy fit of whichever your chosen motor is (longer or shorter)
In order to assure drilling in the correct location, with the cowl off, place some small strips of masking tape in line with the four tabs where we want the cowling screws to go. Pin point on the masking tape where the center of the tab is. Now draw a straight line on the masking tape going back from that center mark, and mark/measure where the hole is relative to the lines. Offer up the cowling to the fuselage, and once in place, use additional masking tape to keep temporarily in place.
Now, on the cowling, using the straight lines and measurements drawn previously, mark where each of the four screws need to go.
Drill out the necessary holes, remove all the masking tapes and re-install the cowl using the four screws.
installation of ancillary components:
Check the correct location of your chosen battery depending on your CG.
Glue the Velcro strip to the battery tray (and battery), as well as threading a velcro strap round the battery tray, assuring a completely secure battery once fully installed.
Finally 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.
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.
Remove the bolts and the nuts should stay in place.
Slide the wheel pants back over the wheel and bolt in place.
SFG – Side Force Generators:
If you choose to use the included SFG’s with quick release system, simply bolt these to the wing-tips using the provided finger screws.
Balancing the CG of airplane:
The CG is 142mm back from the leading edge of the wing at the fuselage. You will also find it marked inside the fuselage, near the wing tube.
Install the included balance rods in their position, attach the canopy and check the balance of the model. Move your batteries accordingly until correctly balanced.
Personal CG preference can be adjusted following the first flight.
Control throw deflections and suggested expo.
General flying:
| Surface | Deflection | Expo |
| Ailerons: | 20º | 40% |
| Elevators: | 20º | 40% |
| Rudder: | 35º | 40% |
Full 3D acrobatics:
| Surface | Deflection | Expo |
| Ailerons: | 38º | 60% |
| Elevators: | 55º | 50% |
| Rudder: | 45º | 50% |
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.
