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. Attach the wing panels to the fuselage. Make sure to connect the leads from the aileron and fl aps to the
appropriate leads from the receiver. Make sure the leads are not exposed outside the fuselage before tightening
the wing bolts. Your model should be fl ight-ready before balancing.
2. The recommended Center of Gravity (CG) location for your model is 3
of the wing for sport fl ying. We recommend a CG location of 4 inches (101.6mm) for STOL fl ying.
3. When balancing your model, make sure it is assembled and ready for fl ight. Support the plane upright at the
marks made on the wing with your fi ngers or a commercially available balancing stand.

at the measurement listed above, then adjusting to suit your particular flying style.
 Nose weight may be required when using lighter weight engines. Move the batteries
as far forward in the fuselage to help reduce the amount of weight required.
CAUTION: You must adjust your aircraft's center of
gravity and balance your model properly before attempting fl ights.

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.
The Timber 110 is capable of extreme 3D aerobatics. For this style of fl ying we suggest working up to maximum
control defl ections and having a dual rate switch. Our extensive testing showed when using the full span aileron option,
having full defl ection for roll on all four surfaces slowed the roll rate. Experiment with full span aileron to achieve the
roll rate desired and don't be surprised if you need to reduce the defl ection to increase the roll rate.

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.
