Landing Gear Installation - Horizon Hobby HANGAR 9 Van’s RV-4 30cc ARF Bedienungsanleitung

4. Attach the ball end to the bracket using an M3 x 10
machine screw and M3 locknut.
5. Check that the tail wheel can rotate freely in the bracket.
Remove any excess paint if necessary so it can rotate
without binding. Attach the tail wheel bracket to the
fuselage using two M3 x 15 socket head machine screws
and two M3 washers. Use threadlock on the screws to
prevent them from vibrating loose.
6. Center the rudder using the radio system. Adjust the
linkage to center the tail wheel, then attach the linkage
to the tail wheel tiller arm using an M3 x 10 machine
screw and M3 locknut. Adjust the linkage as necessary
so the model tracks straight on the runway.
 LANDING GEAR INSTALLATION
1. Attach the landing gear to the fuselage using four M4 x
20 socket head cap screws and four M4 washers. Use
a 2.5mm hex wrench to tighten the hardware. The gear
will angle rearward when installed.
 The installation of the landing gear fairings is
optional. Omitting them does not change the flight
characteristics of your model. Perform only steps 4 through
8 if you decide not to install the landing gear fairings.
2. Use medium grit sandpaper to lightly sand the inside of
the fairings where they will be attached to the fuselage
and wheel pants, as well as inside the fairings where
they will contact the landing gear. Remove any debris
using a paper towel and isopropyl alcohol.

the fairings to the fuselage as there is a right and left
fairing. The fairings that fi t against the wheel pants can
also be checked by holding the wheel pant in position.
Use low tack tape to keep the fairings from moving while
installing the wheels and wheel pants.

centered 3/8 inch (9.5mm) from the end of the axle.

with the axle. With the fl at areas of the axle facing down,
tighten the axle using two 1/2-inch wrenches. The fi rst
wheel collar can be installed centered on the inner fl at on
the axle. Apply threadlock on the setscrews, then tighten
the setscrew on the fl at ares using a 1.5mm hex wrench.
