-
Firmly grasp both sides of the battery connector and pull them apart.
-
Grip the battery and slide it out of the quadcopter body.
-
-
-
Orient the quadcopter so the propellers are on the bottom.
-
Remove the rubber shock absorbers from the motor mounts by hand.
-
-
-
Use the prop removal tool to pry the propellers off the motors.
-
"A" propellers are on the front left and back right motors.
-
"B" propellers are on the front right and back left motors.
-
-
-
Use the wire cutter to remove any customized or aftermarket modifications holding the body together.
-
-
-
Use a Phillips #000 screwdriver to remove the three screws securing the lower body to the frame.
-
-
-
-
Carefully apply upward pressure on one of the motor arms while bending the body downwards to snap the lower body armpice out of place.
-
Repeat this step for all four arms. The lower body will separate from the main frame after snapping the fourth arm out of place.
-
-
-
Use a soldering iron and solder wick to desolder the four motors from the control board.
-
If the connection holds even after removing the solder from the joint, gently pull up on the wire while applying heat to the joint until the wire separates from the PCB.
-
-
-
Using a technique similar to desoldering the motor wires, disconnect the LEDs from the control board.
-
-
-
Use the tweezers to unthread the motor and LED wires from the quadcopter arms.
-
-
-
Use the tweezers to push the motors out of their housings.
-
Once the motor is mostly out of the motor mount, grip it from the top and pull it straight out.
-
-
-
Remove the LEDs using the spudger to widen their housing and nudge them up.
-
To free an LED from its housing, insert the spudger into the top section of the gap in the plastic revealing the side of the LED.
-
Simultaneously twist the spudger to widen the housing while pushing the LED up and out of the frame.
-
-
-
Use the PH000 driver to remove the two screws securing the flight controller to the frame.
-
-
-
The Hubsan X4's Flight Controller (aka Control Board) has a handful of neat components that keep the quadcopter in the air:
-
Hubsan HBS002 Processor
-
Invensense ITG-3050 Integrated Triple-Axis Gyroscope
-
16.000 MHz Quartz Crystal Oscillator
-
3210AP 3-Axis Accelerometer
-
A7105 2.4GHz Wireless Module
-

Will I be able to conect the controller to the receiver with the new motherboard?
It's been my experience the transmitter will bind with what ever quad is ready to bind. I routinely steal my buddy's quad when he plugs it in before he turns his transmitter on.
Just a qiuck note. I burned 2 motherboards with those blue replacement batteries...
hi, while connecting x4 h107c + with 2 wires from battery to the 3 pin on pcb..the motor only spins..no led lights..what can be wrong ?
I have the same issue. The ground being in the center I do not know if the positive is on left or right. Maybe using a small wire to jumb the two to each other?
