V900
™
Sport Airplane
Consult local laws and ordinances before choosing a flying location.
Range Check your Radio System
Before you fly, range check the radio system. Refer to your specific transmitter
instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the first time),
you will normally see the control surfaces react to aircraft movement. In some
flight 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.
Hand Launching
Use the “handle” to hold the aircraft in one hand and the transmitter in the
other. Apply 1/3 - 1/2 throttle and throw the aircraft directly into the wind,
angled slightly up (5 to 10 degrees above the horizon). Climb to a safe altitude
and check the trim.
Flying
For your first flights with the recommended battery pack (SPMX22003S50),
set your transmitter timer or a stopwatch to 4 minutes, land the aircraft. Adjust
your timer for longer or shorter flights once you have flown the model. If at
any time the motor power reduces, land the aircraft immediately to recharge
the flight battery. See the Low Voltage Cutoff (LVC) section for more details on
maximizing battery health and run time.
Landing
Land the aircraft into the wind. Use high rate Elevator for landings. Use a small
amount of throttle for the entire descent.
Keep the throttle on until the aircraft is ready to flare. During flare, keep the
wings level and the aircraft pointed into the wind. Gently lower the throttle
while pulling back on the elevator to bring the aircraft down on its belly.
Using a grass landing area will lesson the chance of damage to the aircraft.
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 finished flying, never leave the aircraft in direct sunlight
or in a hot, enclosed area such as a car. Doing so can damage the aircraft.
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 flight 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 flight 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 flying to LVC will damage the battery.
Tip:
Monitor your aircraft battery’s voltage before and after flying by using a
Li-Po Cell Voltage Checker (SPMXBC100, sold separately).
Repairs
Thanks to the EPO 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.
NOTICE:
Always
decrease throttle at
propeller strike.
Flying Tips and Repairs
PNP Receiver Selection and Installation
The Spektrum
™
AR631 receiver is recommended for this airplane. If you
choose to install another receiver, ensure that it is at least a 4-channel full
range (sport) receiver. Refer to your receiver manual for correct installation and
operation instructions.
CAUTION:
When using a Futaba
®
transmitter with a Spektrum DSM
®
module, you must reverse the throttle channel and rebind. Refer to
your Spektrum module manual for binding and failsafe instructions. Refer to
your Futaba transmitter manual for instructions on reversing the throttle
channel. All flight surfaces must also be checked for the correct direction.
Installation
(AR631 shown)
1. Remove the canopy from the fuselage.
2. Mount the receiver parallel to the length of the fuselage as shown. Use
double-sided servo tape.
3. Attach the appropriate control surfaces to the their respective ports on the
receiver using the chart in the illustration.
CAUTION:
Incorrect installation of the receiver could cause a crash.
