Maintenance and repair

a) Regular Cleaning
The quadrotor helicopter is a very simple but nonetheless well designed flying device. There are no mechanical parts
which need to be lubricated or require special maintenance. However, after each flight operation, you should clean
the quadrotor helicopter of possible dirt (grass blades, dust etc.).
For cleaning, use a dry or slightly damp cloth and avoid contact between water and the electronics, battery and
motors.
Do not fly without covering the electronics. Please ensure that no moisture enters the inner central piece (e.g. wet
grass blades etc.) Never fly when it is raining!

b) Replacing the rotors

If a rotor is damaged through crashing or other action, you must replace this immediately. This also applies should you
detect fine tears or crazing in the rotor. Due to the high speed, material parts could come loose if the rotors are
damaged and this could lead to damage to or endangerment of the environment.
To change a rotor, remove the rotor tip with the spring washers and the faulty rotor. Carry out the mounting of the new
rotor as described in the chapter "Final assembly of the quadrotor helicopter", under mounting of the rotors.
Attention!
Please observe the rotating direction of the respective motor and the choice of the corresponding rotor
without fail. If these are incorrectly chosen, the model will not be able to fly and will act in an erratic way
when next started!

c) Replacing a motor

If a motor is faulty (overheating, electrical fault or bearing failure), this must be replaced. For this purpose, carry out the
following steps as specified:
• Remove the rotor from the faulty motor.
• Remove the upper enclosure and the upper part of the grid frame by loosening the upper screws. Now you have free
access to the motor drivers (driver board). You can also carefully remove these from the clamp for better and easier
handling.
• Note down the colours of the motor connecting cable at the soldering points A, B and C and unsolder the cable.
• Unloosen the screws of the motor clamp and remove the motor from the motor clamp. Pull the cable through the
radial arm.
• Take the new motor and pull the connecting cable through the radial arm. Bolt down the motor and solder the cable
again following the colour table that you noted down.
