Problem
Tail oscillation/wag or
poor performance
Drift in calm winds
Drift in wind
Panic Recovery or Return
to Level does not level
the model
Severe vibration

Possible Cause
Damaged tail rotor, main gear mesh,
loose bolts, vibration
Vibration, damaged linkage,
damaged servo
Normal
Model was not initialized on a level,
still surface
Model was not taken off of a level
surface
Battery strapped too tightly
to the model
Rotating component out of
balance
Verify that the boom support bolts are tight and the plastic
boom support ends are properly adhered to the boom
support rods. Inspect the tail rotor for damage. Verify
that all bolts on the tail assembly are properly tightened.
Verify main gear mesh and ensure no tight spots in the
mesh through full rotation. Replace any damaged or worn
components
Under normal operation the transmitter trims should not
require adjustment and the center positions are memo-
rized during initialization. If you find that trim adjustments
are necessary after take off, verify the balance of all rotat-
ing components, ensure the
linkages are not damaged and make sure the servos are
in proper working condition
The model will drift with the wind but should remain level
in flight. Simply hold the cyclic stick in the necessary po-
sition to keep the model stationary. The model must lean
into the wind to remain stationary, if the model remains
level then it will drift with the wind
Re-initialize the model on a level and still surface
Always lift off from a level surface
Loosen the battery strap
Check the main shaft, tail rotor, main rotor blades, main
frame and adapter for damage, replace as necessary.
Vibration must be minimized for Panic Recovery and Re-
turn to Level functions to work properly
