Edge 540/2.6m
It’s easier to fit the landing gear as the first step, you will find it
easier to handle the model when it’s on its wheels. Drilling the
legs is easier if you have a pedestal drill, and a No 3 centring drill
bit. However this process can easily be done with a hand drill and
a 6.5mm drill bit with due care.

The undercarriage legs for the Composite – ARF Edge 540 are
very strong and very light, thanks to the laminated carbon
manufacturing process that has been used. The legs are held in
place with four - 6mm x 20mm cap head bolts, you will need to
mark and drill the four holes required. The carbon legs are both
identical and can be used on either side. The T-nuts are already
pre fitted to the undercarriage mount plate for you at the factory.
Two bolts are used on each leg, and are inserted from the bottom
of the fuselage.
Place some masking tape on the upper surface of both the carbon
legs and draw a centre line along the top surface. Place a straight
edge on the outer surface of the leg, and measure 38mm from the
edge of the straight edge, and make a mark. The mounting holes
need to be 60mm apart, so make a further mark 60mm from the
38mm mark.
The mounting bolts used are 6mm, so use a 6.2 - 6.5mm drill bit
to make the necessary holes. Using a pedestal drill really makes
the job a lot easier, and you will have less chance of drifting off
the correct drill path. If you are using a hand held drill, it will be
wise to drill a pilot hole first before proceeding to the correct size
drill bit. Take your time and drill straight!
On the lower surface of the carbon leg you see a dimple marking
for the location of the wheel axle. Drill a 6mm hole for the axle,
and a 3mm hole 20mm above the centre of the axle hole, for the
wheel pant retention bolt.
