36) Mount a suitable propeller (not furnished) on your motor.
Be sure to balance the propeller before installation.
OPTIONAL SPINNER: A Spinner is not supplied with this kit be-
cause some flyers may prefer to leave the opening around the
prop shaft clear to allow more cooling air inside the cowling. If
you wish to use a spinner the correct size is 2 inch diameter.
The installation of your electric motor is now completed. Skip the

The KADET SENIOR ARF is a large airplane and is very ade-
quately powered with the 2-stroke or 4-stroke engine sizes sug-
gested. The airplane does not benefit from being over-powered.
Doing this tends to put undue stress on the airframe without any
real gain in performance. This airplane was always intended to
"fly on the wing", not on excessive power.
The engine shown in these instructions is a typical .46 size 2-
stroke engine. The engine is mounted in the upright position, pro-
viding easy access for field adjustments. The engine installation
14
for either 2-stroke or 4-stroke power plants is basically the same.
The main difference is often times the throttle arm location on the
carburetor. The materials provided in this kit should be useful for
almost any 2-stroke engine installation. Installation of a 4-stroke
engine may require some alterations and/or specialized fittings
(not supplied).

37) Start by putting the Fuel Tank together.
a) Locate the Rubber Stopper Assembly. Note that there are
three nylon tubes going through the rubber stopper.
One of the tubes will be used for the Fuel Pickup Tube, which
will then connect to the engine carburetor.
Another tube will be used for the Tank Vent, which is most often
then connected to the pressure fitting on the muffler.
The third tube can be used for a seperate Fill Line if you desire,
or it is more often capped off and the tank filling is done by re-
moving the fuel line at the carburetor and filling through that line.
b) Orient the stopper so that one of the tubes is towards the
top and then bend that tube up at a 45-degree angle. This tube
will be the tank vent line. Do not apply heat to the tube - it will
bend without heat. Just overbend it to nearly 90-degrees and then
let it relax, to see where it will end up. Repeat if necessary until
the tube will stay at 45-degrees.
c) Attach the metal Fuel Pick-Up Weight on one end of the sil-
icone Fuel Line Tubing that goes inside the tank. Cut the other
end of the fuel line tubing to a length that will allow the clunk to
reach the back of the tank, without getting stuck on the walls of
the tank. Test fit in the tank and adjust as necessary. With the
stopper assembly in place, the fuel clunk should sit just in front of
the rear of the tank and move freely inside the tank. If not pull the
assembly back out and trim the tubing back until the stopper
moves freely. The top of the vent tube should rest just below the
top of the tank. It should not touch the top of the tank.
