14. Maintenance and Repair
a) Regular Cleaning
The quadrocopter "Q Pro FPV" 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, carefully lever the damaged rotor from the motor shaft with a suitable tool (e.g. flat-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 (figure 18, items 1 and 2) must have black rotors.
Rotor 1 turns clockwise, rotor 2 turns counter clockwise.
The rear rotors (figure 18, items 3 and 4) must have white rotors.
Rotor 3 turns counter clockwise, rotor 4 turns clockwise.
Do not bend the drive shafts. Bent shafts (e.g. from crashes) influ
-
ence the flight properties negatively due to the vibration that results
and the irritation to the sensors. Motors with bent shaft must be re-
placed.
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 fly and will act in an erratic way
when next started! Loss of guarantee/warranty!
