Balance and Battery Position
It is important to get the balance of your model correct. The initial balance point is
400mm from the point where the wing meets the fuselage. Ensure the wheels are
retracted and the UAT is full. Move your chosen batteries around the fuselage to get
a good balance.
The position indicated above is good
for first flights and may be adjusted,
slightly, to conform to your
respective flying style.
Once balance is achieved, secure the
batteries in the fuselage to maintain
balance. For this build the batteries
are located in the nose cone, this is a
result of using a larger turbine and
heavier thrust tube, no lead was
required to achieve balance.
System Test and Control Throws
Once you are satisfied with the balance test all systems for correct operation, this
includes direction of all control surfaces, retracts, brakes and speed brakes, turbine
ground run and range check.
The following control throws were used for this model:
Ailerons
20 mm up and down with 40% expo
Elevator
45mm up and down with 30% expo
Rudder
As much as possible with 10% expo
LE Slats
15 to 20 mm
Nose wheel
If possible have two settings, one for taxi with large movement and
one for take off with limited movement.
