Flight Trimming

Flying Field Choice

Elevator trim:
Only trim the aircraft at half throttle.
When trimmed correctly, your aircraft
will fly level at half throttle.
• When the aircraft’s nose drifts up or down while the elevator stick is at

neutral (centered) position, push the elevator trim button by one or two
“click” increments OPPOSITE the direction of drift.

• Adjust trim so the aircraft flies straight and level when the elevator stick is

neutral.

Rudder trim:
• When the aircraft drifts left or right while the rudder stick is at the neutral

position (centered), push the rudder trim button by one “beep” increments
OPPOSITE the direction of drift.

• Adjust trim so the aircraft flies straight when the control stick is neutral.

Aileron trim:
• When the aircraft’s wing drops from level on one side while the aileron stick

is at the neutral (centered) position, push the aileron trim button by one or
two “click” increments OPPOSITE the direction of roll.

• Adjust trim so the aircraft flies straight and level when the aileron stick is

neutral.

You can return any trim setting to neutral by pushing the trim button

until the beep signal sounds the middle position. Rising or descending

tones sound when a switch is being pushed.

TIP

Always choose a wide-open space for flying your aircraft. It is ideal for you to

fly at an RC club flying field. Always avoid flying near houses, trees, wires and

buildings. You should also be careful to avoid flying in areas where there are

many people, such as busy parks, schoolyards, or soccer fields. Consult local

laws and ordinances before choosing a location to fly your aircraft.

The site should:

• Have a minimum of 600 feet (183m) of clear space in all directions.

• Stay clear of pedestrians.

• Stay free of trees, buildings, cars, power lines or anything that could

entangle your aircraft or interfere with your line of sight.

Remember, you aircraft at full throttle can cover ground quickly.

Plan on flying in an area that gives you more space than you think you need,

especially with first flights.

Make yourself familiar with your transmitter’s controls and the aircraft’s

response before flying by performing the recommended Control Direction

Test. The flight trim buttons are used to fine tune your aircraft for straight and

level flight. When trimmed correctly, your aircraft flies a straight path with

wings level, steadily climbs at full throttle, maintains a constant altitude at half

throttle, and gently descends at low throttle. SAFE technology must learn your

aircraft trim values to ensure consistent flight behavior. The trim values are

learned when the receiver initially powers up. If you need to adjust the trim

values in flight, set the aircraft to half throttle, make the necessary adjustments

using the flight trim buttons, then keep the throttle position constant and the

aileron, elevator, and rudder controls at the neutral position for 3 seconds. If

you need more than 4 clicks on a trim button to make the aircraft fly straight

and level at half throttle, you should mechanically adjust the control surfaces

as shown in the control surface centering section.

IMPORTANT: For best results, trimming should always be done while flying

directly into the wind using the Intermediate or Experienced Flight Modes.
