The system Xbase-HC3 is the product of initiation of the series of systems robbe-HeliCommand Flybarless for 
piloting helicopters without stabilizer bar and a servo-type H1 or H3-120 °.

Thanks to their low weight, the helicopter models without flybar (Flybarless) are significantly more 
agile and manoeuvrable and have a capacity of about 15% more. In connection with the system-HC3 Xbase 
resulting in an enormous performance with more work in developing the mechanics of brittle weights 
are superfluous. What is striking is the accuracy over the entire range, that is to say both in figures extremely 
dynamic (flying style F3N), the aerobatics (F3C), that stability in the hover. All 
Figures are passed with great fidelity trajectory, that is to say absolutely disturbing influences 
and with a maximum switching behavior. 
Thanks to intelligent control algorithms and optimized, all this is done with minimal effort! 
Silicon MEMS sensors with very high quality of the new generation are the module-HC3 Xbase a perfectly 
able to pass all the aerobatics and 3D simultaneously comprises a gyroscope rotor 
tail very powerful and fast. An external gyro is not essential! In addition to carrying out a command 
symmetrical pair. Increased maintenance effort has been made by mating the rear gyroscopes 
with the characteristics of not controlling the rotor head. 
Naturally the system is also suitable for semi-scale helicopters without weights (at 
two or more blades) or training helicopters without the blades, such as model trains, etc.. with control 
H1 or H3-120 ° Moreover, the system is switchable Flybarless, that is to say, it can also equip the 
"Helicopters normal" with stabilizer bar, in this case, only the function of the tail rotor gyro is active. 
It may equally be implemented on helicopters or electric motor with thermal models 
turbine. It is able to handle all analog servos, and digital brushless servo Narrow-pulse 
(760µs) included for the rear rotor (eg servos Futaba Robbe-S 9251 or BLS 251). 
In the basic version, the most common variants of swashplate H1 and H3-120 ° are available, other 
swashplate types are available with a software update. The system can be Xbase-HC3 
extended through the USB adapter attached and using an Internet update on the entire system functions 
HC3-Xtreme. Without further enhancement, it is possible to use it as a pure gyroscope rotor back when for, example, 
first you want to pilot a new model with a stabilizer bar and weights and a 
Flybarless transformation is planned in the future. In this case, it is not necessary to acquire a gyroscope rotor 
external rear, simply cut rigid function. Swashplate mixing occurs via the Xbase-HC3, 
that is to say that a single transmitter is sufficient. The aluminum housing design and quality are perfectly suited 
quality standards current manufacturers of large helicopters.

The type of building very compact and flexible implementation options to allow this system
implemented on virtually all helicopters.

Content Delivery
• Supports development were reduced to the minimum between
other through the clear dissociation of settings for the
sensitivity of the gyro and the gyro head back via two channels
Additional self.
• USB Direct connection for faster programming, software
comfortable development as well as the installation manual
work are available free on our site unloading.
• The connection cables between the receiver and are Xbase-HC3
plugged on each side.
• Platinum and gold MEMS sensors for the new generation for all
3 axes.
• Possibility of direct connection to new receivers with
a connection to a strand: with output pulse SP serial
eg Robbe FASST receivers R6007SP, S-BUS
Robbe / Futaba and Spectrum / JR Satellites (in this case the main receiver
is superfluous).
The gas outlet and a second output (eg controller (governor), train
retractable landing, lighting, etc..) are directly available
on the system-HC3 Xbase.
