pushrod wire at the carburetor. If necessary, re-bend the wire to
eliminate the bind.
If the throttle servo is binding or “stalling”
because it has too much travel compared to the carburetor travel,
try using your transmitter’s “End Point Adjustment” feature to dial in
the proper amount of travel. If that doesn’t work, you may need to
move the pushrod connectors to different holes in the servo or car-
buretor arms.
You may also need to loosen the pushrod
connectors to re-adjust the overall pushrod length. All or some of
these things may need to be adjusted to get the carburetor
working properly.
The installation of your glow engine is now completed. Skip the
next section on electric motors and proceed directly to “RADIO
INSTALLATION” on page 18.

There are literally dozens of good electric motors and accessories
on the market that are suitable for flying the KADET LT-40. All of
them have their own unique features and dimensions, making
it impossible to write detailed instructions for every brand.
As
mentioned in the beginning of this manual, we will be installing a
Maxx Products #HC3528-1000 brushless outrunner electric motor,
with the Maxx Products #ACC3958 Motor Mount, and a Castle
Creations ESC.
Even if you use other brands, the following
instructions should provide you with enough quidance to
successfully install your electric power system.
IMPORTANT NOTE ON MOTOR MOUNTS: If you are using a
different brand electric motor or motor mount, you need to make
sure that the combination you select can provide exactly 4-1/2”
distance from the front of the prop adaptor to the front of the
firewall (i.e. back of the mount). 4-1/2” is the distance needed for
the cowling to fit properly.
1) There are four sets of “cross-hairs” etched on the front of the
plywood firewall to mark the locations of the mounting holes for the
Maxx Products #ACC3958 Motor Mount. To install this mount on
the firewall you will need to purchase (4) 4-40 x 1/2” Socket-Head
Bolts, (4) #4 Flat Metal Washers, and (4) 4-40 Blind Nuts. Drill the
four mounting holes with a 9/64” or #27 drill bit.
NOTE: If you are using a different mount, line your mount up on the
firewall according to the horizontal and vertical thrust lines that are
etched in the plywood. Then drill appropriate holes where needed
for your mounting bolts.
2) Install the blind nuts on the back of the firewall. The best method
is to use one of your mounting bolts, with a flat washer on it, from
the front side of the firewall to “draw” the blind nut into the back
side. Keep tightening the bolt until the prongs of the blind nut are
completely locked into the plywood. After you get all four blind nuts
in place, apply a little glue around the flanges of the blind nuts to
keep them from coming loose. Be careful not to get any glue in the
threads of the blind nuts.
HELPFUL HINT: It’s never easy putting a blind nut on the backside
of the firewall of a pre-built model. Here’s a handy trick! Take a
stick of scrap balsa wood - 1/4” sq. x 10”-12” long works well in
most cases - and put a piece of doubled-up tape (any kind) on the
end, and then stick the blind nut to the tape. With this stick you can
reach inside the nose of the airplane and hold the blind nut in
position while you screw in the mounting bolt from the front of the
firewall. If the model structure doesn’t allow a straight shot at the
location, cut an angle on the end of the stick to allow you to hold
the blind nut at the correct angle.
