It is very important that you make sure the control surfaces (rud-
der, elevator and ailerons) are at 0 degrees when the transmitter
control sticks and trim switches are centered. Turn on your trans-
mitter and receiver. Make sure the rudder, elevator and aileron
sticks are centered and the trim switches are centered. Make sure
the throttle, aileron, rudder and elevator travel adjusts are set at
100%. Use a ruler to place against the control surfaces to see if
there are any deflections from the center (0 degrees).
Adjustments to the control surfaces can be made by threading the
clevis in or out on the control rod. Threading in causes the sur-
face to move toward the rod. Threading out causes the surface to
move away from the rod. Set the control surfaces (except throttle)
to 0 degrees.
Before each flight, check the screws and nuts that secure the
metal plate holding the motor in place on the metal motor mount.
Make sure the prop nut is tight by first removing the screws hold-
ing the front of the spinner. Once the spinner is removed, use
your prop wrench to make sure the prop nut is tight against the
propeller and washer on the crankshaft of the engine.
The motor high speed and low speed needle valves have been
pre-set at the factory. Refer to the motor operating instructions on
how to fine-tune the carburetor. Make any adjustments to the
high-speed needle valve in small increments (one or two “clicks”
at a time). You should be able to easily start the engine with the
present carburetor settings. Read through the engine operating
instructions prior to starting your engine.
The Xtra Easy has been balanced at the factory. If for some reason
changes are made in battery location or a different engine is
installed, you will need to make sure the balance of the aircraft is
correct before attempting to fly it. The balance point (or center of
gravity) of the Xtra Easy is a range of 3

" to 3

" from the lead-
ing edge of the wing. If you have to add weight to the nose or tail,
use the stick-on variety sold at your local hobby shop.
Make sure the clevises are connected to the outer hole of the
control horn of the rudder and elevator control horns and that the
clevis keepers are in place.

To achieve these throws with 100% travel adjust in the transmitter,
the linkages need to be hooked up in the following manner:
• Elevator:
At the control surface, use the outermost hole on the
control horn. At the servo, use the hole 8mm out from the cen-
ter at the servo arm. This is the innermost hole on the “X” arm.
• Rudder/Nose wheel:
At the control surface, use the outer-
most hole on the control horn. At the servo, use the 8mm hole
out from the center of the servo arm. This is the innermost hole
in the “X” arm. The nose wheel is located 11mm out from the
center on the servo arm and at the outermost hole on the nose
wheel steering arm.
• Ailerons:
At the torque rod, the nylon horn bracket needs to
be screwed on the torque rod such that it is 17mm from the sur-
face of the wing. At the servo, use the hole 8mm out from the
center at the servo arm. This is the innermost hole on the “X”
arm. This gives the exact throw given above.
• Throttle:
At the carburetor, use the innermost hole. At the
servo, a location of 12mm from center should be used.
