Flying Tips and Repairs

PNP Receiver Selection and Installation

During your ﬁ rst ﬂ ight, trim the aircraft for level ﬂ ight at 3/4 throttle with ﬂ aps up.

Make small trim adjustments with your transmitter’s trim switches to straighten the

aircraft’s ﬂ ight path.

After adjusting the trim, do not touch the control sticks for 3 seconds. This allows

the receiver to learn the correct settings to optimize AS3X performance.

Failure to do so could affect ﬂ ight performance.

In Flight Trimming

3 Seconds

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

Place the aircraft facing into the wind. Set your transmitter in low rate and use

your ﬂ aps switch to drop the ﬂ aps to takeoff or “half position”. Gradually increase

the throttle to ¾ and steer with the rudder. Flaps make takeoffs shorter. As the tail

comes off the ground, pull back gently on the elevator. When airborne, ﬂ ip your

gear switch to raise your landing gear. Climb to a comfortable altitude and then ﬂ ip

your ﬂ aps switch to level the ﬂ aps.

Flying

For your ﬁ rst ﬂ ights with the recommended battery pack (SPMX50006S30), set your

transmitter timer or a stopwatch to 4 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

Land the aircraft into the wind. Use high rate Elevator for landings. Use a small

amount of throttle for the entire descent. Lower the throttle to ¼ and ﬂ ip your ﬂ aps

switch to deploy the ﬂ aps to the landing or “full down position”. Flaps will make

the landing approach steeper and slower, and allow for a smoother landing. Flip

your gear switch to lower your landing gear. This will slow the aircraft further.

Keep the throttle on until the aircraft is ready to ﬂ are. During ﬂ are, 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 wheels.

If landing on grass, it is best to hold full up elevator after touchdown and when

taxiing to prevent nosing over.

Once on the ground, avoid sharp turns until the plane has slowed enough to

prevent scraping the wingtips.

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.

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 (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.

AR637T Port Assignments

BND/PRG = BIND

1 = Throttle

2 = Ailerons

3 = Elevator

4 = Rudder

5 = Gear

6 = Flaps

The recommended receiver for this aircraft is the Spektrum AR637T. If you choose

to install a different receiver, ensure that it is at least a 6-channel full range

receiver. Refer to the manual of your chosen receiver for correct installation and

operation instructions.

AR637T Installation

1. Lift the back of the canopy to remove the canopy from the fuselage.

2. Attach the appropriate control surfaces to the their respective ports on the

receiver using the table at the right.

3. Using double-sided servo tape,(not included) mount the receiver to the ﬂ at area

behind the battery compartment, as shown. The receiver should be mounted

in the orientation shown, parallel to the length of the fuselage, with the label

facing up and the servo ports facing the front of the aircraft. The orientation of

the receiver is critical for all AS3X and SAFE technology setups.

CAUTION: Incorrect installation of the receiver could cause a crash.
