3- Assembly

Main landing gear assembly:

Position the fuselage upside down and screw on the carbon undercarriage to the fuselage using the nuts and bolts provided.

Screw the wheel axles on to the landing gear, and then slide on the wheels and secure in place with the provided grub screws.

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, 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. 

Insert the blind nuts on the inside of the fuselage and secure the tail wheel with the bolts provided. Attach the spring at one end to the metal arm on the tailwheel and the other end to the underside of the rudder itself using the small woodscrew 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.

Installing the control 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 control 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 contriol 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:

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.

When using Pilot-RC servos, no extension wire is necessary as these come with 50cm wire as standard.

Use the included string and tabs to 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: 

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.

Attach the ball links to the rudder servo horn and pull through any excess pull pull wire until both sides are tight and without slop. Tension should be similar to that of the strings on a guitar.

With everything correctly in place, crimp the small copper tubes firmly onto the wires to permanently fix the wires in place, before sliding over the heat shrink.

ELEVATOR servo installation: 

Locate and cut the covering where the servo will be installed, at the rear of the fuselage, just in front and 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.

Route the servo wire through the fuselage and screw the servo in place.

Centre the servo with your transmitter, attach the servo arm and connect the servo to the elevator with the pushrods provided.

MOTOR installation: 

The Edge 540 87″ is provided with the firewall not yet mounted, so you can install it at the appropriate distance for your particular engine, without the need for stand-offs.

The engine box however does come with the appropriate engine incidences applied, so wherever you need to install your firewall, make sure that this is paralell to the edges of the engine box in order to maintain the correct incidences.

Measure the distance between your engines mounting plate and prop hub

Temporarily place the firewall in roughly what will be its final location, then place the cowl on the model and measure the gap between the firewall and spinner position.

Adjust the placement of the firewall forward or backwards until both measurements match and mark the firewalls final location on the engine box.

Due to the engine incidence, in order for the prop hub to exit the cowl in the correct location (in the center) you will need to mount the engine slightly off-centre on the firewall.

New versions of the Edge include this new “off-centre line” laser engraved on the firewall.

Using these lines, mark the necessary locations for the engine bolt holes and drill accordingly.

If your engine uses a rear admission carburettor, you will also need to drill a large hole in the firewall in order for the carburettor to fit through.  For this we recommend the use of a circular saw drill bit, centred on the “off-centre line” and then lightly tweaked with a mini-drill sanding drum where required

Once completed, securely screw your engine to the firewall using your preferred method bot, nut or blind nut method.

Reinstall the firewall back into the model, following its location as marked out earlier and lightly screw into place using the nuts and bolts provided.

Once done, remove the screws and firewall, apply Epoxy to the engine box where the firewall will be mounted, and reinstall and tighten all the nuts and bolts to securely fix the firewall in its now final, screwed and glued position.

Secure the engines ECU to the engine box, we recommend on top of the firewall however this may vary depending on your installation.

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. Draw a straight line on the masking tape going over the holes, and mark/measure where the hole is relative to the lines.

Install the cowling, tightening the top bolt. Place additional masking tape on the cowling, and with a ruler continue the straight lines drawn previously.

Measure back to the marked point where the holes are, and then remove the cowl and drill out the two necessary holes with a 2,5mm drill bit.

Re-install the cowl using the top and bottom bolts.

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.

Make sure that all ancillary components are securely fastened or tied down and can not come loose in flight.

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, simply bolt these to the wing-tips using the provided finger screws.

Balancing the CG of airplane:

The CG is 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:


Full 3D acrobatics:


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.
