Adjusting the Throttle Opening
1. Lower the throttle and center the throttle
trim.
2. Adjust the length of the throttle linkage until
the throttle is open 1mm.
3. Move the throttle stick up to confirm the
throttle opens. If the throttle does not
open, reverse the throttle channel in your
transmitter.
4. Move the throttle stick and throttle
trim down to confirm the throttle closes.
5. If you reversed the throttle channel in your
transmitter and you are using a 2.4GHz radio
system, you must re-bind your radio system
to set the correct failsafe position.
Attaching the Fuel Lines
Crankcase
Pressure Line
Fuel Inlet Line
1. Connect medium diameter fuel tubing to the
carburetor and the fuel tank supply line.
2. Connect the medium diameter fuel tubing
to the vent line in the fuel tank. Route the
other end of this line to the outside of the
fuselage.
A. If using a three-line tank, connect medium
diameter fuel tubing to the third line and
route this line to a convenient location for
fueling/de-fueling your model.
B. If using a two-line tank, connect a “T”
fitting inline with the carburetor supply
line and route one side of the “T” to a
convenient location for fueling/de-fueling
your model.
We recommend using a fuel filler like the one
included in the Hangar 9
®
Fuel Filler with “T”
Fitting and Overflow Fitting (HAN116), which
also includes a vent line connector. This
package makes it convenient to setup your fuel
system whether using a two- or a three-line fuel
tank. We also recommend using medium
diameter FKM fuel tubing for all plumbing in
your fuel setup.
Attaching the Propeller and Spinner
1. Remove the prop nut and prop washer from
the crankshaft.
2. Install the spinner backplate, followed by
the propeller, prop washer and prop nut.
3. Cover the propeller with a cloth and use an
adjustable wrench to tighten the prop nut.
4. Install the spinner cone. Make sure the
spinner cone is not touching the propeller.
Trim the propeller opening if necessary.
5. Tighten the spinner screw(s) to secure the
spinner cone.
