15. Maintenance and Repair
a) Regular Cleaning
Thequadrocopter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, 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 red rotors of the model point forward.
Thefrontrotors(gure25,items1and2)areatthe"front"for
this model and must have red rotors. Rotor 1 turns clockwise,
rotor 2 turns counter clockwise.
Therearrotors(gure 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)
inuencetheight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yandwillactinanerraticway
when next started! Loss of guarantee/warranty!
