Edge 540/2.6m
A DA100/120 has a bolt separation pattern of 70mm across
and 80mm from top to bottom. Make your marks as shown in
the picture above.
When you are satisfied with your engine position markings, drill
your mounting holes. Drill a 3mm pilot hole first, then use a
7mm drill bit to enlarge the hole to suit the 6mm T-nut. Using a
6mm bolt and a washer pull the T-nuts into position.
The engine standoff’s need to be 54mm on the RH side and
58mm on the LH side (pilots view), to achieve the correct thrust
line. If you are using the SWB standoff’s this is easy to achieve
using the adjustment washers supplied. Simply use one large
adjustment washer per LH stand off, and one medium, per RH
standoff.
As the standoffs are over 50mm it is wise to wrap the standoffs
in carbon cloth. This will assist in eliminating excess vibration
due to the length of the standoffs. You simply layup some
carbon cloth with some epoxy and wrap the carbon around the
standoffs, as shown in the picture. When cured the standoffs
will now be like a unified dome rather than individual standoffs.
You will be surprised at how much vibration this will reduce.
