Sukhoi SU 31—2.75m/2.6m Page|9
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, or to suit your chosen engine.
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 posi-
tion.
Mount your engine using the alloy standoff s supplied in your hardware pack.
