gAS ENgINE INSTALLATION
Mount the Engine
A template is provided on page 53 for mounting the Fuji-Imvac
BT-43 EI-2 engine and pictures taken show the installation of
this model gas engine. If another model engine is used, the
engine manufacturer may provide a mounting template to
use on the firewall. The gas engine installation will be similar
for most model engines.
Because of the possibility of ignition engines creating
radio noise, we use a plastic pushrod for the throttle
servo installation. This isolates the engine and any
radio noise from the servos. This is an IMPORTANT
selection, and we cannot recommend strongly
enough that you DO NOT change this pushrod to a
metal pushrod. All radio equipment–including throttle
servo, receiver battery, receiver on/off switch, servo
leads–should be mounted at least 10" [254mm] away
from anything related to the ignition/gasoline engine.
Any material used between the engine and the radio
equipment is STRONGLY recommended to be plastic,
nylon, or otherwise non-metallic and nonconductive
to minimize ignition noise transmission.
o 1. Cut the template out on page 53 for mounting the Fuji-
Imvac BT-43 EI-2 engine. Use tape or spray adhesive to hold
the template to the firewall. Align the vertical and horizontal
lines on the template with the lines on the firewall.
o 2. Use a large T-pin or a wire sharpened on the end to
transfer each bolt hole mark on the template into the firewall.
o 3. Measure the outer diameter of the boss on the blind nuts
you will use to mount the engine (gasoline engine mounting
hardware is not included). The 10-32 blind nuts we use will
require a 1/4" [6.3mm] bit. Use the appropriate bit for your
hardware to drill holes at the four marks you made on the
firewall. To reduce tear-out, make pilot holes with a smaller
bit first, then finish the holes with the correct diameter bit.
Insert a 10-32 blind nut into the back of each hole. Use a
10-32 x 1-1/4" [32mm] SHCS and a few #10 flat washers to
draw the blind nuts tight against the back of the firewall.
