Center Of Gravity; Control Throws - Horizon Hobby HANGAR 9 Aermacchi MB-339 Bedienungsanleitung

CENTER OF GRAVITY

An important part of preparing the aircraft for flight 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 flying 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. Assemble the model and ready it for flight. Make sure to connect the leads to the appropriate leads from the
receiver. Make sure the leads are not exposed before tightening any hardware. Your model should be flight-ready
before balancing.
2. The recommended Center of Gravity (CG) location for your model is 4
of the wing against the fuselage.
3. When balancing your model, make sure it is assembled and ready for flight. Support the plane inverted at the
marks made on the wing with your fingers or a commercially available balancing stand.
Î The overall CG range for this model is 4 / –6 inches (114–152mm). We recommend starting

at the measurement listed above, then adjusting to suit your particular flying style.
CAUTION: You must adjust your aircraft's center of
gravity and balance your model properly before attempting flights.

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 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.

Flap Throw
The full flap throw creates a lot of drag slowing the model very quickly. Test at a safe altitude.
