6. Drill a 9/64” hole in the firewall in position with
the throttle arm. Insert the 3.25mm nylon sleeve
in the hole. Install an e-z connector in the throt-
tle arm and install the 1.25mm x50cm pushrod.
drill your fuel line holes at this time.
5. Align the motor on the firewall. Center the
engine on the off center vertical line and the hor-
izontal line. Drill holes on the marks using a
3/16” drill. Insert the blind nuts into the rear of
the fire wall and tighten using washers and lock
washer (use thread lock).
Glue the nylon sleeve to bulkhead
7. Mount the throttle servo in the servo tray
ahead of rudder servo. Position the servo so
that the servo arm is on the same side as the
throttle pushrod. This may vary depending on
the engine used. Glue the nylon sleeve to the
bulkhead to prevent flexing of the rod. Install
another e-z connector on your servo arm and
attach to the throttle pushrod.
Fuel Tank
1. Locate the fuel tank and hardware.
2. Assemble the cap by inserting the screw
through the large washer, through the black rub-
ber and threading into the small washer on the
back side. Insert the three metal fuel lines into
the holes in the cap. The short line will be the
pickup line and will have the silicone tubing
attached to the back end. On the other end of
the silicone tube install the clunk. This should be
adjusted in length so the clunk is about 1/4” off
the bottom of the tank. One of the long tubes
should be bent so it rest against the top of the
tank. This is the vent line. The other tube will be
the fill line. Insert the stopper in the tank and
mark the fill, vent, and pickup line so you don’t
get them mixed up later. If you are using a YS
engine which pressurizes the tank, you should
wrap the tank in strapping tape with a couple of
loops going around the cap to make sure it does
not blow off.
