Edge 540/2.6m
The ailerons on the Composite Arf Edge 540 differ from what has
been up to now, normal for Composite Arf models, the ailerons
are centre hinged! The ailerons now use a hinge tube just like the
rudder and elevators. The ailerons are huge, and require 2 brass
hinge tubes, to cover the length of the aileron.
The 2 brass tubes can be left as 2 separate pieces, or you may
elect to join the 2 pieces with a piece of 1/8
th
brass tube. The 1/8
th
tube is a snug fit in the 4mm tube and soldering should not be
necessary. Leaving the tubes separated will not create any
problems, it’s your choice!
To secure the brass hinge tube at the wing root, it is very easy to
drill a 1.5mm hole at the end of the tube and insert an R clip,
which in turn is secured with a small servo screw. At the wing tip,
you can again use tape, or the 4mm plastic plug as used in the
elevators and rudder.
This section is mandatory, not an option!
It is important to semi balance the aileron to assist in
preventing flutter. You will need to epoxy 20 grams of lead
into the elevators balance tab. This is a simple procedure
and will not detract from the performance of your model. Use
the same procedure used when assembling the elevators.
However there is an increase in the weight to 20 grams!
Servo Hatches:
The aileron servos need to be attached to the hatch covers on the
bottom of the wing. Plywood mounts are provided for this
purpose. Once assembled these mounts will need to be epoxied
onto the servo hatch. Assemble the mounts and for now, just CA
them.
You will need to mark out the placement for the servo mounts on
the hatch covers. Be careful that you have the hatch cover in the
correct orientation. The servo hatch sits on a plywood retainer
built into the wing. This small ledge is about 5mm wide. You will
need to mark this area on the servo hatch as shown. The servo
mount is mounted slightly off centre in an effort to get the servo
output shaft as close to the centre of the servo arm slot as
possible. The servo needs to be installed with the output shaft
toward the leading edge of the wing.
Place the servo mount so as your servo arm fits nicely between
the edges of the cut out. When satisfied with its position epoxy in
place, making sure you epoxy the inside corners of the of the
Ailerons
