13Remote control set description
• Ring-limiter: functions similar to swashplate limi-
tation but is used for control of up to three Voith-
Schneider drives in ship models.
• Channel sequencer for automating servo motion
sequences of up to three servos, e. g. to automate
the lowering of landing gear or to extend/retract
drives in self-launching gliders.
Model programs
• Model type icon: graphic model type indicator
(fixed-wing / helicopter)
• Transmitter operating hours timer
• Flight phase switch assignments: six switches, two
with a priority function. Every switch combination
can be named freely. This makes the number of
flight phases independent of the number of flight
phase switches.
• Tail type normal, V-tail, Delta/flying-wing and 2 HR
Sv 3+8 (which immediately makes two coupled
elevator servos available without using free mixers
or dual mixers)
• Flap count 4 AIL/4 FL: Full support of eight wing
servos, even without use of free mixers (standard
feature only on the twelve-channel
mc-20 HoTT
transmitter; can be unlocked at extra cost on the
mc-16 HoTT)
• Expanded transmitter control menu: single-sided
centre offset facility. With the exception of the
trims, all transmitter control elements can be as-
signed as transmitter controls. Option of assigning
two switches to each input to act as a genuine
three-stage function.
• Wing mixers: New concept for the multi-flap menu
to simplify settings of one to eight wing servos on
a flight-phase specific basis in a comprehensible
manner without requiring the use of free mixers
• »Logical switches«: this function permits two
switches to be coupled as »and« or »or« logic
functions. The result can be employed as a virtual
switch. Typical application: The activation of certain
functions should only be possible in conjunction
with other functions, e. g. wheel brake can only be
activated when the landing gear is down. A num-
ber of functions which are normally independent
of one another, are to be put in their base settings
by way of an »Emergency switch«. This program
automation can be activated by multiple switches
that also select the appropriate program. (Stand-
ard only on the
mc-20 HoTT, optional on the
mc-16 HoTT.)
• Flight phase switching cutoff delay: the delay time
can be switched off for individual channels on a
flight-phase basis (e. g. for motor off in electric
models or to activate/deactivate helicopter head
lock). (Standard only on the
mc-20 HoTT, op-
tional on the mc-16 HoTT.)
• Expanded servo centre adjustment range: now
+/-125 %
• Number of flight phases: fixed-wing: 7, helicopter:
6 + AR
• Phase trim available on all axes of fixed-wing mo-
dels
• Servo assignments can be swapped at the re-
ceiver output
• Additional functions planned; implementation via
software update.
General HoTT features
• Simple, extremely fast binding for each model
• Ultra-fast re-binding even at maximum range
• Any number of receivers can be bound to provide
additional channels (max. 32 channels)
• Range: test and warning function
• Low-voltage warning
• GR-16 and GR-24 receivers used in SAME mode
can simultaneously address a maximum of four
servos as a block, with a frame rate of 10 ms (digi-
tal servos only!)
• Thanks to cycle time reduced down to as little
as 10 ms, extremely short response times are
achieved.
• Real-time telemetry analysis on the transmitter
screen. As an option, telemetry data can also be
displayed on the SMART-BOX.
• Selectable cycle time: 10 ms or 20 ms/30 ms, de-
pending on receiver and operating mode
• Channel mapping in the receiver allows free distri-
bution of control functions.
The travel distance and rotation direction settings
integrated into the receiver make it possible, for
example, to match up mapped servos with one an-
other.
• The programmable fail-safe functions »Hold«,
»Off« and »Move to preset positions« that are built
into the receiver for every individual servo channel
can be set separately.
