Stick deadzone (E)
the entire tail mechanics running smooth and without binding. Make sure that the
rudder servo is strong enough and that it is supplied with sufficient power (long
supply leads cause high voltage loss!). Check that the rudder servo does not get
powerless at maximum servo deflection. This can happen if the pulse range of the
servo is exceeded. The cause for lacking tail thrust also can be that the tail rotor
blades are too small or too soft, or because the rotation speed of the tail rotor is too low!
To gain better tail gyro performance also check for correct servo horn length. If the tail
gain in general is very low and the rudder tends to oscillate very easy move the linkage
ball on the servo horn further inwards to the center. If on the other hand you have a
very large amount of tail gain and the tail gyro still does not seem to be capable to hold
the tail rotor in any flight condition, move the linkage ball on the servo horn further out
from the center, to get faster response speed when the gyro needs to control the rudder.
Do not change the rudder rate consistency at menu point D in case the tail gyro does not
hold well on abrupt directional changes. The rudder rate consistency doesn't compensate
for sudden movements! In this case increase the gyro gain (if possible) or use the help
of RevoMix feature (point F).
106.3 Stick deadzone (E)
The deadzone defines the range around the very center of the stick in which MI-
CROBEAST PLUS will not react to stick inputs. Unfortunately, some on the market
available transmitters have the problem that when the sticks are brought back to the
center position after a stick input, they aren’t exactly at the same center position as
before. This generates a continuous deviation on the corresponding function, although
the stick seems to be at mid position. This deviation is interpreted as a small input by
MICROBEAST PLUS which leads to an unwanted drift on one or more axis. Especially
you can see and feel this in hovering flight when the helicopter is turning slightly to
one or another direction all the time. This makes it difficult to have precise hovering as
it is hard to find a stick position at which no input is sent to MICROBEAST PLUS.
This can be very dangerous as it may cause the helicopter to tip over when trying to
take off or it can cause the pilot to loose control over the helicopter at all! So increase
the stick deadband stepwise just until you don‘t see such effects. Note that as a result
of large stick deadband there will be a wide range around mid stick position in that
MICROBEAST PLUS will not react to stick inputs. This will make the control more in-
precise. So if using “large“ or “very large“ deadband is necessary, we recommend to let your
transmitter get checked by its manufacturer for damaged or worn out stick potentiometers.
