SERVOS DO NOT RUN AND LED FLASHES RED

See chapter LED

FINE MOVEMENTS WITH DIGITAL SERVOS ARE HEARD

No problem, these result from the control loop, made audible by modern super-fast servos.

JERKINESS OF TAIL SERVO

If the tail gyro‘s auxiliary channel is at neutral position, it will stay around the switching point between heading hold and normal mode,

and may randomly switch it on and off. Use either a positive or a negative signal in the tail gyro channel to dene the mode and obtain

a “useful” gyro gain.

NO CALM FLIGHT ATTITUDE ON THE TAIL AND/OR HEAD

Extreme vibrations (visible or tangible only) on the housing (especially with gasser/nitro motors) → Observe installation notes. Or

non-correct center signals (check in DIAGNOSE).

TILTING DURING PIROUETTES (LURCHING OR TUMBLING MOTION)

• Housing not mounted exactly perpendicular (or aligned with) to the rotor shaft?

• With a neutral signal (when in DIAGNOSE), swashplate not levelled exactly perpendicular to the rotor shaft?

• Self-leveling active?

TILTING DURING PIROUETTES, ONLY DURING STRONG WIND OR IN HIGH SPEED

• Equalize aileron and elevator travel.

• Use similar gain setting for aileron and elevator.

WEAK HOLDING TAIL

• Travel limit and gyro gain correctly set?

• Rpm high enough?

TAIL UNEXPECTEDLY SWINGS OUT TO THE SIDE

• Tail drive (belt or shaft) slipping?

• Too high an angle of attack on tail (stall)?

• Enough power on the tail (rpm high enough)?
