4. Position the engine on the mount so the distance from
the firewall to the front of the thrust washer measures 7"
[178mm]. Mark the location of the engine on the mount. The
Great Planes “Dead Center
™
” Hole Locator (GPMR8130)
works well for this. Drill through the marks you have made
with a #29 or 9/64" [3.6mm] drill bit. Tap each hole with an
8-32 tap.
❏
5. Install the engine to the mount with four each, 8-32 x
1" [25mm] socket-head cap screws, #8 lock washers and #8
flat washers.
❏
6. Install the muffler onto the engine. Next, install the
throttle servo into the servo opening on the side of the
firewall box. Drill a 1/16" [1.6mm] hole through each of the
mounting holes. Remove the servo and then install and
remove a servo mounting screw into each hole. Apply a
couple drops of thin CA into the holes to harden the threads.
When the glue has cured permanently, mount the servo.
❏
7. Install a brass screw-lock pushrod connector, nylon
retainer ring and a 4-40 x 1/4" [6mm] socket-head cap screw
onto the outer hole of the servo arm and the throttle servo
arm. Bend a .074 x 12" [305mm] threaded rod to fit from the
throttle servo arm to the throttle arm. When bending the wire
be sure that you have clearance between the pushrod and
any of the engine/muffler components. Metal contact may
create radio interference.

Installation instructions for the Fuji-IMVAC BT-43 EIS (or
other brands of gasoline engines)
The following instructions are specific to the Fuji-IMVAC
BT-43 EIS. Other gasoline engines may be able to use a
mounting procedure very similar to the Fuji-IMVAC so take a
minute to review these engine mounting instructions. Pay
close attention the dimensions for spacing the engine from
the firewall when mounting your particular brand of engine
and be sure to use the mounting template for your particular
brand of engine.
(Please Note: The mounting hardware and pushrods for the
installation of a gasoline engine are not included in the kit.
All of the bolts and pushrods are readily available at the local
hobby shop).
❏
1. Mark a line on the both sides of the engine box centering
the line on the firewall tabs. Measure up from the tabs 1/2"
[13mm] and make a crossing line. Drill a 1/8" [3mm] hole on
the marks, drilling into the firewall approximately 1/2" [13mm].
