Patrick from KDE Direct Shared with us some information about the new KDE Direct 700 Series XT Main Rotor Head System:
KDE DIRECT 700 SERIES XT MAIN ROTOR HEAD SYSTEM
The new 700 Series XT Main Rotor Head System provides the most
innovative and highly‐engineered control mechanics to instill confidence in
any flying style. Every detail was scrutinized and continually reviewed to
provide the ultimate system for Flybarless flight control, without fear of the
common failure modes (boom strikes, bolt shear, misalignment, etc.) that
plagues other competitive offerings in the market.
OPTIMIZED MAIN ROTOR HEAD SYSTEM
The entire Main Rotor Head System is optimized for center‐of‐gravity
alignment to the tail boom axis (for true, on‐point rolls) and further
prevention of boom‐strikes on Electric and Nitro models. This was
achieved by slightly raising the height of the rotor head plane and
increasing stiffness in critical areas of the design.
STRENGTHENED HOUSING DESIGN
Geometry has been increased in key areas for
significantly raised strength and stiffness characteristics
in flight, without additional weight or undue material.
OPTIMIZED MAIN ROTOR GRIP ARMS
Arms extended further from the main shaft and
optimized to the mounting location for perfect flight
mechanic alignment and increased servo resolution
(resulting in significantly improved Flybarless control).
In addition, custom Grade 12.9 M4 Socket Head Collar
Screw and Locknut design used to prevent chances of
bolt shear, loosening, or other detrimental failures.
INNOVATIVE CLAMPING MECHANISM
Design includes a M4/M3 clamping mechanism for a
rock‐solid lock of the housing to the main shaft. This
key design aspect provides unprecedented accuracy
and crisp feel (no rocking/bobbing effects) for all types
of flying styles.
ROBUST MAIN GRIP CONTROL LINKS
FEA‐optimized design provides unprecedented strength and
light‐weight characteristics for accurate pitch control.
Ball links are infinitely‐adjustable with an innovative M3
Socket Head Set Screw and M3 Locknut design;
providing limitless ability for perfect pitch alignment
and a failure‐free hold for endless flights.
