Edge 540/2.6m

Wheel Pants:

The wheel pants are recessed to fit against the carbon
undercarriage legs, you will need to epoxy in place the “U” shaped
milled plywood pieces to the inside of the wheel pants. Rough up
the inner surface of the wheel pant with some sand paper, prior to
applying epoxy.  This section of the wheel pant is reinforced with
Kevlar, and the recessed moulded section is quite prominent and
easy to locate. Epoxy the plywood “U’ piece in place and set aside
until cured.

After the epoxy has cured, locate the dimple in the recess at the
inside outer surface of the wheel pant. You need to drill at this
point a hole large enough to accommodate a 6mm T-nut, a 7.5mm
drill bit will do nicely.

You will notice that the 6mm T-nut protrudes well past the surface
of the wheel pant. At this point you can elect to cut down the
threaded portion of the T-nut, or simply let the T-nut stand proud
inside the wheel pant. If you elect to let the T-nut stand proud,
don’t forget to fill the space between the T-nut and the ply with
epoxy and micro balloons (if using Hysol you will not need micro
balloons).

When you have the 6mm T-nut secured in place trial fit the wheel
pant to the landing gear leg. At this point you can use the 3mm
hole that you drilled earlier as a drill guide to drill the wheel pant.
When you have done this insert a 3mm T-nut into place in the
wheel pant.

Locate the 6mm x 70mm axle cap head axle bolt, wheel collars,
6mm flat washers and 6mm nylock nuts. The positioning of the
wheel collars is shown in the picture opposite. You will now need
to drill a hole in the outer surface of the wheel pant big enough for
the axle bolt to pass through.

Assemble the wheel and axle onto the landing gear leg, ensuring
that the wheel remains able to rotate freely. Please note if you are
using Dubro wheel, you will need to drill out the axle hole to 6mm.
