1. Balance Your Model (Cg)

2. Connect the marks on the firewall to locate the center

of the firewall.

3. Cut the Engine Mount Template from page 19 of this

manual and tape it to the firewall as shown above. At the

locations on the template, drill four 3/16" (4.7mm) holes in

the firewall for the engine mount blind nuts.

4. Install four 6-32 Blind Nuts to the inside of the

firewall. Pull the blind nuts into the back side of the firewall

using a 6-32 machine screw (with a flat washer under the

head of the bolt). Fit the two halves of the Engine Mount

together. Use four #6 Flat Washers and four 6-32 x 3/4"

Machine Screws to secure the engine mount to the

firewall. Do not tighten the screws at this time, as the mount

must be adjusted for the engine.

5. Test fit your engine into the mount. Adjust the width of

the rails to fit the engine snugly. Tighten the mount screws

to allow marking the engine mounting holes without moving

the rails.

6. Position the engine on the engine mount rails so the

propeller thrust washer (or spinner backplate) is 4-1/2"

(114mm) ahead of the firewall. Use a Great Planes Dead

Center

™

Hole Locator (GPMR8130 not included) to scribe

the four engine mount holes onto the rails. You may use a

sharpened piece of wire to scribe the mount holes and

then, use a center punch at the marks to prevent the drill bit

from wandering. Drill 3/32" (2.4mm) pilot holes through the

rails. Be sure to hold the drill perpendicular to the rails. If

you have access to a drill press, this is a good tool for this

purpose. Put a drop of oil into each hole. Use four #4 x 5/8"

Sheet Metal Screws to secure the engine to the mount.

7. Drill a 3/16" (4.7mm) hole in the firewall for the throttle

pushrod. The hole location will depend on whether you are

installing a 2-stroke or 4-stroke engine.

8. Roughen the outside surface of the 11-3/4" (298mm)

Throttle Pushrod Tube with coarse grit sandpaper. Insert

the pushrod tube through the hole in the firewall. Push it in

until about 1/4" (6mm) of the tube is left exposed forward of

the firewall. Use medium CA to glue the tube to the firewall,

but leave it free inside the fuselage until the servos are

installed.

RADIO INSTALLATION

1. Use the following sequence for mounting the servos

into the servo tray.

A. Install rubber grommets and brass eyelets in the servos

using the provided sketch.
