 Step 2
Using a drill and 1/16-inch (1.5mm) drill bit, drill through the
template and through the firewall for the mount that fits your
particular engine.
 Step 3
Remove the template from the firewall. Use a drill and 7/32-
inch (5.5mm) drill bit to enlarge the holes in the firewall.
 Step 4
Use four 8-32 x 3/4-inch socket head bolts, four #8 washers
and four 8-32 blind nuts to secure the mount rails to the
firewall. Tighten the screws using a 9/64-inch hex wrench or
ball driver.
Important : Make sure to use threadlock on all metal-
to-metal fasteners.
 Step 5
Slide the engine into position between the engine mount
rails. Use a pencil to mark the location for the throttle
pushrod wire on the firewall.
 Step 6
Remove the engine from the rails. Use a drill and 5/32-inch
(4mm) drill bit to drill a hole through the firewall for the
throttle pushrod tube.
 Step 7
Use medium grit sandpaper to roughen an area that is 2 1 /

to 3 inches (63 to 76mm) from one end, as well as the last
1-inch (25mm) of the pushrod tube as shown.
 Step 4
Use a drill and 1/4-inch (6mm) drill bit to drill four holes
in the bottom of the engine mounting box so the ignition
module can be secured to the fuselage.
 Step 5
Place a piece of 1/4-inch (6mm) foam between the ignition
module and fuselage. Use two 12-inch (305mm) tie wraps to
secure the module to the fuselage.
Important : Make sure not to install the tie wraps over
the throttle pushrod tube. This could cause the pushrod
to bind and cause the throttle servo to run the receiver
battery down prematurely.
 Step 6
Make all the connections between the ignition battery, switch
and module according to the instructions provided with the
engine. Make sure to secure any loose wires so they do not
interfere with the operation of the engine or radio system.
