Maintenance of Helicopter
The most important thing for a permanent optimal success with
your new helicopter is to check and maintain every component af-
ter every use. Below you will find some general steps for mainte-
nance:
Main rotor checklist:
1) Regularly check the main rotor on wear. Check all components
of the main rotors, make sure there is no tolerance between linka-
ges. All parts should run smoothly. No bearings should be knocked
out.
2) The O-rings lose their elasticity over time. Replace them and any
worn part on a regular basis.
3) As soon as the helicopter flies slower and does not respond
spontaneously to pitch and gas pulses review the following parts
immediately:
- Ball bearings
- Main rotor blades
- All plastic parts of the main rotor
4) Check very carefully whether the main rotors are balanced.
Both blades must be exactly equal, an increased wear can occur
and the helicopter might
reacts different in difficult flight situations if not balanced.
5) The directions of the swash plate must be exactly examined.
The levers should not be bent or cracked. The swashplate must
always be able to follow your controls exactly. Replace the swash-
plate when you
discover an error.
Hull and chassis checklist:
1) Check the bearings and the support of the main rotors.
After about 100 flights, you should replace these parts with new
ones. If you frequently
perform 3-D flights, you need to maintain more often.
2) The bearings in the hull should be checked, cleaned and lubri-
cated after about 50 flights. Carry out the same procedure for the
gears. Make sure everything sits secure and nothing has loosened.
3) Also, the belt drive for the tail rotor must be regular checked
and examined if any damages occurred. It should not be stretched
or worn, no tooth should be worn. If the belt drive is not in 100%
working condition, it has to be changed.
Linkages and connections
Make sure the linkages run smoothly and are tight at the same
time. Only this can ensure that the helicopter flies optimal. If you
break a rod, the helicopter will crash inevitably. Replace faulty lin-
kages.
Tail rotor system
1) Clean the tail rotor on a regular basis, especially if you take off
and land in high grass.
2) Regularly inspect the tail rotor if it functions correctly. If you find
knocked out bearings, they must be replaced.
3) After about 50 flight, carefully disassemble the tail rotor and
clean all components. All worn parts should be replaced.
4) Also the tail rotor blades need to be check if they have any da-
mage. If they are damaged, they need to be replaced. The tail ro-
tors need to run smooth because if not, the whole helicopter might
vibrate.
Note: Only a well-maintained helicopter protects you against acci-
dents and the loss of the model.
