Flying Tips and Repairs
Consult local laws and ordinances before choosing a fl ying location.
Range Check your Radio System
Before you fl y, range check the radio system. Refer to your specifi c
transmitter instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for
the fi rst time), you will normally see the control surfaces react to
aircraft movement. In some fl ight conditions you may see oscillation
(the aircraft rocks back and forth on one axis due to overcontrol).
If oscillation occurs, refer to the Troubleshooting Guide for more
information.
Takeoff
Flying
For your fi rst fl ights with the recommended battery pack
(SPMX22004S30), set your transmitter timer or a stopwatch to 3
minutes. After 3 minutes, land the aircraft. Adjust your timer for longer
or shorter fl ights once you have fl own the model. If at any time the
motor power reduces, land the aircraft immediately to recharge the
fl ight battery. See the Low Voltage Cutoff (LVC) section for more details
on maximizing battery health and run time.
Landing
Remember to take off into the wind. When you’re ready, set your
rudder control rates to high and point the model straight down the
runway, hold a bit of up elevator to keep the tail on the ground to
maintain tail wheel steering, then gradually advance the throttle. As
the model gains speed, decrease up elevator allowing the tail to come
off the ground. One of the most important things to remember with a
tail dragger is to always be ready to apply right rudder to counteract
engine torque. Gain as much speed as your runway and fl ying site will
practically allow before gently applying up elevator, lifting the model
into the air.
To initiate a landing approach, lower the throttle while on the
downwind leg. Continue to lose altitude, but maintain airspeed by
keeping the nose down as you turn onto the crosswind leg. Make your
fi nal turn toward the runway (into the wind) keeping the nose down
to maintain airspeed and control. Level the attitude when the model
reaches the runway threshold, modulating the throttle as necessary to
maintain your glide path and airspeed. If you are going to overshoot,
smoothly advance the throttle (always ready on the right rudder to
counteract torque). Climb out to make another attempt. When the
model is a foot or so off the runway, smoothly increase up elevator
until it gently touches down. Once the model is on the runway and
has lost fl ying speed, hold up elevator to place the tail on the ground,
regaining tail wheel control.
NOTICE:
If a crash is imminent, reduce the throttle and trim fully. Failure
to do so could result in extra damage to the airframe, as well as damage
to the ESC and motor.
NOTICE:
After any impact, always ensure the receiver is secure in
the fuselage. If you replace the receiver,
install the new receiver in the same
orientation as the original receiver or
damage may result.
NOTICE:
Crash damage is not covered
under warranty.
NOTICE:
When you are fi nished fl ying,
never leave the aircraft in direct sunlight
or in a hot, enclosed area such as a car.
Doing so can damage the aircraft.
NOTICE:
Always
decrease throttle at
propeller strike.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a
charge. The ESC protects the fl ight battery from over-discharge using
Low Voltage Cutoff (LVC). Before the battery charge decreases too
much, LVC removes power supplied to the motor. Power to the motor
reduces, showing that some battery power is reserved for fl ight control
and safe landing.
Disconnect and remove the Li-Po battery from the aircraft after use
to prevent trickle discharge. Charge your Li-Po battery to about half
capacity before storage. During storage, make sure the battery charge
does not fall below 3V per cell. LVC does not prevent the battery from
over-discharge during storage.
NOTICE:
Repeated fl ying to LVC will damage the battery.
Tip:
Monitor your aircraft battery’s voltage before and after fl ying by
using a Li-Po Cell Voltage Checker (EFLA111, sold separately).
Repairs
Thanks to the EPO foam material in this aircraft, repairs to the foam
can be made using virtually any adhesive (hot glue, regular CA, epoxy,
etc). When parts are not repairable, see the Replacement Parts List for
ordering by item number. For a listing of all replacement and optional
parts, refer to the list at the end of this manual.
NOTICE:
Use of CA accelerant on your aircraft can damage paint.
DO NOT handle the aircraft until accelerant fully dries.
