13. Maintenance and Repair
a) Regular Cleaning
The quadrocopter "Q" is a very simply built ight model. There are no mechanical parts that need to be lubricated
or require special maintenance. However, after each ight operation, you should clean the quadrocopter of possible
contamination (wool threads, hair, dust etc.).
For cleaning, use a dry or slightly damp cloth and avoid contact between water and the electronics, rechargeable
battery and motors.
b) Replacing the Rotors
If a rotor is damaged in a crash or other action, replace it immediately. This also applies if there are any ne tears or
grazing 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 replace a rotor, carefully lever the damaged rotor from the motor shaft with a suitable tool (e.g. at-head screw-
driver) and replace it by a new one. Installation must be performed with the necessary caution and the corresponding
care.
For orientation, put the quadrocopter onto your work surface so that the black rotors of the model point forward.
The front rotors (gure 12, items 1 and 2) must have black rotors. Rotor 1 turns
clockwise, rotor 2 turns counter clockwise.
The rear rotors (gure 12, items 3 and 4) must have white rotors. Rotor 3 turns coun-
ter clockwise, rotor 4 turns clockwise.
Do not bend the drive shafts. Bent shafts (e.g. from crashes) inuence the ight
properties negatively due to the vibration that results and the irritation to the sensors.
Motors with bent shaft must be replaced.
The rotating direction is marked at the bottom of the rotors ("A" or "B").
The rotors marked "A" must be installed on the rotors that turn to the left (counter
clockwise).
The rotors marked "B" must be installed on the rotors that turn to the right (clockwise).
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 y and will act in an erratic way
when next started! Loss of guarantee/warranty!
