The bavarianDEMON 3SX is a high-quality, compact designed Flybarless
system (Rigid) and replaces the mechanical flybar on the rotor heads of
all current RC helicopters. Additionally this unit features the
well-known and patented Horizontal mode (self-leveling), which brings
the heli back to horizontal attitude anytime you let go off the
sticks.Moreover, the system is equipped with several safety features,
leveling the heli back even while in hard 3D-maneuvers like Tic-Toc or
PiroFlip with a speed never seen before.
These brand new features
enable a pilot to learn 3D flying in the most safe way ever, speaking of
a kind of “real-flight simulator” on highest level.
stabilization sensitivity (gain) as well as engaging or disengaging this
function can be controlled via an auxiliary channel from the
transmitter while in flight.
Because they are lighter, helicopter
models without auxiliary paddles are much more agile and maneuverable,
and are approx. 15% more powerful. In combination with the 3SX, huge
performance is delivered, without the need to adjust the fragile paddle
The all-round precision is outstanding, whether it is
the extremely dynamic maneuvers (F3N flying style), aerobatics (F3C), or
hovering stability. All maneuvers are performed with directional
stability, i.e. with no disruptive influences at all, and with maximum
stopping performance. This is achieved with minimum need for adjustment
thanks to the intelligent and optimized control algorithms.
means of the latest-generation high-quality silicon MEMS gyros, the 3SX
has full 3D capability, whilst boasting a top-quality, ultra-fast tail
gyro. No external gyro is required. In addition, a symmetrical torque
control unit is in place there. The resultant further increase in
retention force in the tail was possible because the tail gyro is
internally coupled with the pitch data of the rotor head control unit.
course, the system is also suitable for flybarless scale helicopters
(twin- and multi-blade) as well as all other flybarless helicopters such
as trainers, etc., and, due to the possibility of engaging the
Horizontal mode at any time, perfectly suitable for beginners.
3SX can be used for helicopters with electric motors or
nitro/combustion engines as well as turbine models (in case of a turbine
inside a scale canopy, please see the safety instructions in the manual
All current analogue, digital and brushless servos
are supported, including narrow-pulse servos (760s) for the tail (e.g.
Robbe-Futaba S 9251 and BLS 251). All current swashplate variants are
also supported, including four swash servos and virtual swashplate
rotation (H1, H3-90°, H3-120°, H3-140°, H4-90°, H4-90°+45°).
system can also be used as a pure tail gyro, without the need of any
additional accessories. Especially if a new heli project is planned,
first using a flybar, later on switching to a flybarless head, the
purchase of an external tail gyro is not necessary. Simply set the Rigid
gains in the PC software to „0“, so the Rigid mode is disabled. The
swash mixing is done by the 3SX, so even a simple transmitter can be
The CNC-milled aluminium casing and the high-quality design
comfortably meet the current quality standards of major helicopter
manufacturers. The highly compact construction and the flexible
installation possibilities enable use in almost every helicopter, from
micro-copters through to 3.5m scale helicopters.
• Set-up work is
reduced to a minimum, partly because of clear separation of the
sensitivity settings for the head and tail gyros in independent
• Can be used as pure tail gyro without the need of additional accessories.
• Direct USB connection for fast programming; the easy-to-use set-up software comes as standard.
• The connecting cables between the receiver and 3XS are plugged in on both sides.
• Gold-plated circuit-board and the latest-generation MEMS gyros for all 3 axis.
The 3SX features direct connection to new single-cabled receiver
systems: SP serial pulse/PWM output, e.g. the Robbe FASST receiver
R6007SP, robbe/Futaba S-BUS and Jeti/Spektrum (no DSMX)/JR-satellites
(main receiver not applicable). Consequently, the motor/gas-servo output
as well as a second output (e.g. for governor, lighting, retractable
landing gear, etc.) are available directly on the 3SX.
• The 3SX is equipped with a flash memory and can therefore be updated in service to the latest software level.
