CONTROL THROWS
1. Turn on the transmitter and receiver of your model. Check the movement of the rudder using the transmitter.
When the stick is moved to the right, the rudder should also move right. Reverse the direction of the servo at the
transmitter if necessary.
2. Check the movement of the elevator with the radio system. Moving the elevator stick toward the bottom of the
transmitter will make the airplane elevator move up.
3. Check the movement of the ailerons with the radio system. Moving the aileron stick to the right will make the
right aileron move up and the left aileron move down.
4. Use a ruler to adjust the throw of the elevator, ailerons and rudder.
These are general guidelines for general sport and aerobatic fl ying from our own fl ight tests. You can experiment with
higher or lower rates to match your preferred style of fl ying.
Travel Adjust and Sub-Trims are not listed and should be adjusted according to each individual model and preference.
Always install the control horns 90 degrees to the servo center line. Use sub-trim as a last resort to center the servos.
Always re-bind the radio system once all the control throws are set to keep the servos from moving to their endpoints
until the transmitter and receiver connect.

CENTER OF GRAVITY
An important part of preparing the aircraft for fl ight is properly balancing the model. The Center of Gravity range
supplied here is a guideline based on testing. Deviation from the measurements we provide is possible and may result
in a model that suits your fl ying style better. Start with the recommended Center of Gravity, then feel free to experiment
with different balance points. We advise adjusting progressively and cautiously.
1. When balancing your model, make sure it is assembled and ready for fl ight but with the wings and wing struts
removed. The tail section and all tail supports should be installed.
2. The recommended Center of Gravity (CG) location for your model is 4
5
/
16
inches (110mm) behind the leading edge
of the wing. Mark the location on the sides of the fuselage using a felt-tipped pen.
3. Hold the plane upright, placing your fi ngers at the marks you made on the fuselage. View the model from the side
(you may need a helper). If the model is properly balanced, the stabilizer will be level.
4. If either the tail or the nose hangs low, then the opposite end needs to be heavier. To reduce the amount of weight
you need to add, fi rst reposition batteries or other accessories inside the fuselage as far forward or back as
needed to improve the balance. If you must add weights, always secure them well so they cannot move during
fl ight.
 The overall CG range for this model is 1
5
/
8
– 8 inches (40 – 200mm). We recommend starting at the
measurement listed above and then adjusting the Center of Gravity to suit your flying style.
 Due to the short nose and long tail of the Carbon Cub FX-3, it is not uncommon for them to require
nose weight in order to achieve the correct balance to suit some flying styles. For a soft and sedate
“feel” it may be necessary to add between 2–4 lbs (0.91–1.8 kg) to the front of the aircraft.
CAUTION: You must adjust your aircraft’s center of
gravity and balance your model properly before attempting fl ights.
