Gas Engine Installation
Plan your engine mounting by determining the
length of the engine, standoff, spacers or washers
needed. The distance between the cowl and the
firewall is 6.375” (162mm). There may be slight
variation in the manufacturing process of the cowl
so please check this dimension. Remember to add
a gap between the spinner and cowl. The kit does
contain engine standoffs but these may not be
suitable for every engine.
Shown below is the supplied DA60/70 or
3W-50
engine mounting template in place. You may
modify this template for other engines or layout
mounting holes directly on the firewall. Notice the
two centerlines on the firewall. One is the firewall
center and the other represents the engine
mounting centerline offset to compensate for the
built in engine thrust angle. When lying out
mounting holes use the offset centerline. This will
position the spinner in the center of the cowl
opening.
The engine should be mounted with bolts through the
engine mounting plate, a flat washer, the fire wall,
through another flat washer, then a nylon lock nut.
Use the throttle servo pocket on the bottom side of the
engine box for twin cylinder engines. (Fuselage shown
upside down.)
