Preflight
Check Your Radio
Before going to the field, be sure that your batteries are fully
charged per the instructions included with your radio. Charge
both the transmitter and receiver pack for your airplane. Use the
recommended charger supplied with your particular radio system,
following the instructions provided with the radio. In most cases,
the radio should be charged the night before going out flying.
Before each flying session, be sure to range check your radio.
See your radio manual for the recommended range and
instructions for your radio system. Each radio manufacturer
specifies different procedures for their radio systems. Next, start
the motor. With the model securely anchored, check the range
again. The range test should not be significantly affected. If it is,
don’t attempt to fly! Have your radio equipment checked out by
the manufacturer.
Note: Keep loose items that can get entangled in
the propeller away from the prop. These include
loose clothing, or other objects such as pencils and
screwdrivers. Especially keep your hands away from the
propeller.
Double-check that all controls (aileron, elevator, rudder and
throttle) move in the correct direction.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e. the correct direction and with
the recommended throws). Test run the motor and make sure
it transitions smoothly from off to full throttle and back. Also
ensure the engine is installed according to the manufacturer’s
instructions, and it will operate consistently.
Check all the control horns, servo horns, and clevises to make
sure they are secure and in good condition. Replace any items
that would be considered questionable. Failure of any of these
components in flight would mean the loss of your aircraft.
Flying the Sobré
Flying the Sobré is about as fun as it can get at the park. A very
light wing loading and extreme control throws make for some
exciting 3D flying. Verify that your CG is at the correct location
as per the manual and that you have your rates set up to your
liking. Verify that all control throws are in the correct direction
and the motor spins in the correct direction as well.
Point the model into the wind and add some throttle trim until
the motor begins to turn. This will be your flight idle. Now, apply
power slowly. You will find the model will become airborne very
quickly and at a low speed. This model excels at flying slow and
easy, as well as slow and extreme. Trim the model for level flight
at half throttle. Only use full throttle for maneuvering. Do not fly
this model fast or at full throttle in level flight. Doing this will result
in the flight controls fluttering and a potential catastrophic failure
of the airframe.
You will find you can adjust the CG to your liking by moving the
battery pack fore or aft on the wing.
To land the Sobré just reduce the throttle to idle and feed in up
elevator until the model settles into a slightly nose high attitude.
Gently fly the model down to the landing spot with a final flair at
touchdown. You will find the model will have a very short roll out.
We hope you enjoy the Sobré as much as we do.
Happy landings.
