Control Horn Settings

The table to the right shows the factory settings for
the control horns. Fly the aircraft at factory settings
before making changes.
After fl ying, you may choose to adjust the linkage
positions for the desired control response.
CAUTION: When these are incorrectly
connected for the pilot's skill level, unexpected
aircraft response to controls can result. This can
cause damage to the aircraft and personal injury.

Dual Rates

To obtain the best fl ight performance, we
recommend using a DSM2/DSMX radio capable
of adjustable Dual Rates. The suggested settings
shown here are the recommended starting settings.
Adjust according to the individual preferences after
the initial fl ight.
NOTICE: Do not set your transmitter travel adjust
over 100%. If the TRAVEL ADJUST is set over
100%, it will not result in more control movement, it
will overdrive the servo and cause damage.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The aircraft's ESC
protects the fl ight battery from over-discharge
using Low Voltage Cutoff (LVC). Once the battery
discharges to 3V per cell, the LVC will reduce the
power to the motor in order to leave adequate
power to the receiver and servos to land the
airplane.
When the motor power pulses, land the aircraft
immediately and replace or recharge the fl ight
battery.

Tip: For the fi rst fl ight, fl y the model in low rate.
Always disconnect and remove the Li-Po battery
from the aircraft after each fl ight. Fully charge
your Li-Po battery before storing it. Make sure
the battery charge does not fall below 3V per cell.
Failure to unplug a connected battery will result in
trickle discharge and damage to the battery.
For your fi rst fl ights, set your transmitter timer or a
stopwatch to 4 minutes. Adjust your timer for longer
or shorter fl ights once you have fl own the model.
NOTICE: Repeated fl ying to LVC will damage the
battery.
