D 1. Trial fit the five parts together to check how they fit
(see the plans and the photos). Sand the parts as necessary for
a good fit. Assemble the parts with 5-minute epoxy, and wipe
up the excess glue inside the "box" before it sets up.
DRILL ENGINE MOUNT (Great Planes
MM40 or MM60 mounts)
D 1. Align the engine on the mount and mark the mount-
ing hole locations on the mount. At the marked locations,
accurately drill 7/64" (or #36) holes. NOTE: If you have
access to a drill press, use it for drilling these holes to insure
that they are drilled vertically.
D 2. Now you may use one of the following methods to
attach your engine to the mount:
Method 1: Screw the #6 x 3/4" sheet metal screws
(provided in the kit) through the engine mounting flange and
into the mount. When first installing these screws, put a drop
of oil into each screw hole.
Method 2: Cut threads in the holes you just drilled using
a 6-32 tap and tap wrench. If you use this method you'll have
to supply your own bolts (6-32 x 1" socket head cap screws)
for attaching the engine to the mount
INSTALL SERVOS, HORNS AND
PUSHRODS
D 2. Hold the engine mount on the 2-cycle firewall in the
location shown on the plan, and mark the boll locations
through the mount. Drill 5/32" holes at the bolt locations,
then install the 6-32 blind nuts inside the box. You may tap
the blind nuts in with a hammer, or pull them in using a 6-32
bolt (with a flat washer under the head of the bolt). Apply CA
glue or epoxy around the rim of the blind nuts to hold them
permanently in place. Test the threads of each blind nut with
a 6-32 bolt
D 3. Study the cross-section drawing of F-l (on the fuse
plan), and, by measurement, mark the location of the "box"
on F-l (Note that the box and mount are offset 5/32"
toward the left side of the fuse). Glue the firewall box to F-
1 with epoxy. Apply a small fillet of epoxy around the
perimeter of the box, for added security.

D 1. Study the plans to determine the location of the
aileron servo cutout. Mark the location on the bottom of the
wing and cut an opening in the fiberglass and sheeting slightly
larger than your servo. CAUTION: Do not cut into the wing
spars or shear webs!
D 2. Remove a sufficient portion of the W-l ribs to fit
your servo, leaving "shelves" on which to glue the 1/8" ply
rails. (See the plan to determine the depth). NOTE: A
Dremel Moto Tool with a 1/8" router bit is excellent for this,
but it may also be done with an Xacto knife and a long-nose
pliers.
D 3. Make two servo rails from the 1/8" ply die-cutting
scrap, and glue them in place. (See the side view of the
aileron servo installation on the plan).
