Defi nition of terms
Control functions, transmitter controls, function inputs, control channels, mixers, switches, control switches, Smart-Box
To make it easier for you to understand the mx-10
HoTT manual, the following section contains defi nitions
of many terms which crop up again and again in the
remainder of the text.
Control function
The term "control function" can be thought of as the
signal generated for a particular function which needs
to be controlled - initially independent of its subsequent
progress through the transmitter. In the case of fi xed-
wing model aircraft the control functions include throttle,
rudder and aileron, whereas collective pitch, roll and
pitch-axis are typical of those used for helicopters. The
signal of a control function may be assigned directly, or
to several control channels simultaneously via mixers. A
typical example of the latter is separate aileron servos or
a V-Tail. The essential feature of a control function is its
infl uence on the mechanical travel of the corresponding
servo.
Transmitter control
The term "transmitter control" refers to the mechanical
elements on the transmitter which are operated directly
by the pilot. Their movements in turn generate corres-
ponding movements in the servos, speed controllers etc.
at the receiver end. The transmitter controls include the
following:
• The two dual-axis stick units for the control functions
1 to 4; for both model types ("fi xed-wing" and "helicop-
ter") these four functions can be interchanged in any
way you wish using the "Mode" function, e. g. throttle
left or right, without having to re-connect the servos.
The dual-axis stick function for throttle (or airbrakes) is
often referred to as the Ch 1 (Channel 1) control.
• The switch for channel 5
When a proportional transmitter control is operated,
the servo or servos follow the position of the control
directly, whereas a switched channel provides just the
two or three set servo positions.
Function input
This is an imaginary point on the signal path, and must
not be considered the same as the point on the circuit
board where the transmitter control is connected! The
two menus "Stick mode" and "Transmitter control
settings" affect the course of the signal "after" this point,
and it is possible (and likely) that there will be differences
between the number of the transmitter control (as stated
above) and the number of the subsequent control chan-
nel.
Control channel
There is a point on the signal path where the signal con-
tains all the control information required for a particular
servo – this may be directly generated by a transmitter
control or indirectly via a mixer – and from this point on
we call the signal a "control channel". This signal is only
affected by any adjustments carried out in the "Servo
settings" menu before leaving the transmitter via the RF
module. Once picked up at the receiver, this signal may
be modifi ed by any settings made in the Telemetry menu
before fi nally passing to the corresponding servo in the
model.
Mixer
The transmitter's software includes a wide range of mixer
functions. Their purpose is to enable a control function to
affect multiple servos at the branching point of the mixer
input, or alternatively to allow several control functions to
affect one servo. For more information please refer to the
numerous mixer functions of the Smart-Box as described
on page 119 of the manual.
Switch
The standard toggle switch for channel 5 moves the
connected servo to the min./max. position.
Smart Box
The optional Smart-Box allows the use of many other
HoTT functions such as:
• transmitter voltage display with programmable warning
threshold
• Receiver Temperature
• Servo travel
• Channel Mapping
• Mixer settings
• Signal quality
• Receiver Voltage
• Servo neutral position
• Cycle time
• Channel-dependent fail-safe settings
• Servo test
see the section „telemetry" on page 113.
