Apex Digital GD-90C User manual

IMPORTANT
Insert the battery into the quadcopter and connect the
plug. The two indicators will begin flashing. Place the
quadcopter on a flat surface.
Important: Be sure the surface is flat and level. The
quadcopter needs to calibrate it’s orientation.
PLEASE PRACTICE SIMULATEDFLIGHT BEFORE ACTUAL FLYING
Before you are familiar with the unit, please don't pilot it . Read the instruction carefully to get
familiar with the direction controls.
1. Checking that propellers are securely attached to the motors. Pull the throttle down to prevent takeoff.
2. Place quadcopter in a clear open field and point the tail towards yourself.
3. Practice operating the control sticks (as shown below), and repeat practicing “Throttle
high/low”, “ Left/right ”, “Forward/backward”, and “bank left/right”.
4.Strong impacts can jam the motors, using a long flat nose plier to unjam to rotor.
5.The simulation flight practice is very important, please keep practicing until you are comfortable with the controls.
After turn on the quadcopter
the LED indicators keep
flashing but the quadcopter
does not respond.

PACKAGE CONTENTS REMOTE CONTROL FUNCTIONS
The propeller system is a precision instrument that may nee d to be repaired or r eplaceedfrom
time to time f or optimal flight function. Crash landing fro m high-speed ae rial flights maycause
damage to propeller blades.
1.The aircraft has four blades, two white colors on front, and two black colors on back (see the
diagram below).
2.When replacing the propeller blades, make sure to match both the color of the blade and the
indication letter on the blade.
3.Replace broken blades with the correct blade.
Charge with our dedicated charger.

CAUTION
CAUTION
FLIGHT ADJUSTMENT AND NOTICE FOR BEGINN E RS
Check if the screws and blades are firmly tightened
Check if t he transmitter and h elicoptera re fully charged.
Make su re that n o peopleor obstructions are in thevicinity.
You must first practice hovering to fly safely, this is a basi c
flight action(meaning keep the helicopter in mid air i n a fixed position)
Please stand approximately 6ft diagonally behind the helicopter.
1. The throttle is on the left hand, push the throttle a little up to raise the copter to
your line of sight then pull down a little to let the quadcopter slowly down to the
floor.Repeat until you can easily and quickly control the altitude.
2.Hovering flight practic: Raise the quadcopter to a certain height then hover at
that altitude.
3.Try increasing and decreasing the altitude quickly this time while still
maintaining control.
1. Use the right stick to practice moving forward and backwards.
2. Use the left and right stick to practice turns and banking.
Slowly raise the throttle stick and observe just as the helicopter lifts off the ground if it
leans in a direction. Youcan use the trim to correct this action.
1. Adjustmentof Left/Right trim
Just before the quadcopter lifts-off, the nose leans left/right.
When it leans right adjust the trim to the left side.
When it leans left adjust the trim to the right side.
2. Adjustment of Forwards/Backwards trim
Just before the quadcopter lifts-off, the nose leans forward/backwards.
When it leans forwards adjust the trim down.
When it leans backwards adjust the trim up.
3. Adjustmentof Roll trim
Just before the quadcopter lifts-off, the body rolls left/right.
When it rolls right adjust the trim to the left side.
When it rolls left adjust the trim to the right side.
If a MicroSD card is not installed the
LEDs will flash 5 times. When a
MicroSD card is intalled the leds will
stay illuminated.

TROUBLE SHOOTING DURING FLIGHT
Solution
No response after the
battery is connectedto
the quadcopter.
Main rotor continues to
spin after landing
Helicopter rotor spins but
unable to take off.
The helicopter still keeps
turning after rudder triming
or inconsistent speed during
left/right pirouette.
1. The blades haven’t been
installed in the right place.
2. Rotor blade deformation
3. Didn’t calibrate the flight.
1. Replace the main wing
Replace the main motor
2. Change blade
3. Correct the level refer to P6
Throttle stick not on the
lowest position
1.Check whether the blade
assembled correctly or not.
2.Helicopter battery depleted.
Make sure the Throttle stick is
on the lowest position
Check whether it is low power Charging the helicopter
The quadcopter shifts
forwards/ backwards.
The trim is not even. • Trim the elevator back to center.
• Restart the remote control.
1.Rotor blade turns off
2.Rotor blade deformation
1.Change replacement rotors
2.Tighten the Rotors
