15. Maintenance and Repair
a) Regular Cleaning
The quadrocopter is a very simply built flight model. There are no mechanical parts that need to be lubricated or
require special maintenance. However, after each flight 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 fine 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, screw the damaged rotor (small screw in the middle) from the motor shaft 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 yellow rotors of the model point forward.
The front rotors (figure 25, items 1 and 2) are at the "front"
for this model and must have yellow rotors. Rotor 1 turns
clockwise, rotor 2 turns counter clockwise.
The rear rotors (figure 25, items 3 and 4) must have black
rotors. Rotor 3 turns counter clockwise, rotor 4 turns clockwise.
Do not bend the drive shafts. Bent shafts (e.g. from crashes)
influence the flight properties negatively due to the vibration
that results and the irritation to the sensors. Rotors with bent
shaft must be replaced.
The rotating direction is marked on the rotors ("A" or "B"). The
mark "A" or "B" points up.
The rotors marked "A" must be installed on the rotors that turn rightwards (clockwise).
The rotors marked "B" must be installed on the rotors that turn leftwards (counter 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 fly and will act in an erratic way
when next started! Loss of guarantee/warranty!
