The TYRANN 450 3D helicopter is a fine model constructed of
precision components. In order to maintain good performance
you must make sure that every component is in good working
Main rotor
1. Please inspect the main blades, fly bar, main shaft to see
that they are not distorted and that they run true. Any erratic
vibrations or wobble is an indication that something is either
bent or not in balance. Vibrations can affect the quality of
the flight and can lead to loss of control or a crash. If you
observe any damage replace the parts with new parts of the
correct type. Inspect the blades for any damage, if you find
any cracks or chips discard the blades and replace with new
ones prior to flying your helicopter.
Caution
Before you fly, please balance the main rotor blades carefully
since this will determine if the helicopter will perform properly.
4. Please make sure the control arms move freely without
binding or sticking. The screws that hold the arms in place
should be just tight enough so that they don't bind or
prohibit movement.
Frame check
1. Please change the main shaft bearing after 100 flights or
as soon as you notice any play or slack in the bearings to
main shaft. Should you notice any abnormal noise or drag it
is advisable to replace the bearings with new ones
immediately.
2. Please take apart the free-wheel bearing and clean and
lubricate it with light machine oil after 50 flights. If there is
any damage to the free-wheel bearing you should replace it
with a new one.
Control sticks check:
Please make sure that every servo is connected and tight,
control linkages should be tight but not bind or drag, If you find
a binding or a servo that drags it should be repaired/replaced
with a new servo/linkage.

order. Poor maintenance may cause damage and accidents; we
suggest that you perform the preflight checklist prior to flying
your TYRANN 450 3D helicopter.
2. Please check whether the main rotor O-rings are tight and
that the head i s not loose at the blade grips. Over time the
rubber O-rings can soften which can lead to poor flight
performance. If the O-rings become soft replace them with
new ones.
3. Check the pitch range on the rotor blades to make sure there
is enough pitch for flight. Check the shaft bearing for wear
and looseness, replace with new bearing if they become
worn.
5. Make sure that the swash plate does not bind or touch the
frame with full servo movements.
3. You should replace the tail drive toothed belt if you discover
any damage to the drive train or tail rotors. After some time
the tail drive belt will fatigue and should be replaced.
