HobbyKing KK2.1HC Multi-Rotor Hard Case Flight Con

The next evolution of the rotor revolution is
here!! The KK2.1HC (Hard Case) is packing new
found power with updated sensors, memory, header
pins, hard case and remote programmer.

The KK2.1HC is the next big evolution of the first
generation KK flight control boards. The KK2.1HC
was engineered from the ground up to bring
multi-rotor flight to everyone, not just the
experts. The remote LCD screen and built in
software makes installing and setup easier than
ever. The screen and programing buttons have been
relocated to a remote plug-in programmer and a
hard case installed, this makes the KK extremely
durable. The plug in programmer uses the exact
same format as the onboard version and can be
plugged in at anytime for a quick value change.
This new design allows the KK to be installed in
frames where access to the onboard buttons and
screen was an issue, you can even leave the cable
plugged into the KK side and run it out for access
to the programmer. The Hard case still retains the
standardized 45mm mounting holes and has the
buzzer is now internally mounted. Mounting
locations and damage to the LCD screen is a thing
of the past.

A host of multi-rotor craft types are
pre-installed, simply select your craft type,
check motor layout/propellar direction, calibrate
your ESCs and radio and you're ready to go! All of
which is done with easy to follow on screen
prompts!

The original KK gyro system has been updated to an
incredibly sensitive 6050 MPU system, making this
the most stable KK board ever and allowing for the
addition of an auto-level function. At the heart
of the KK2.1HC is an Atmel Mega644PA 8-bit AVR
RISC-based microcontroller with 64k of memory. An
additional polarity protected header has been
added for voltage detection, so no need for
on-board soldering. A handy piezo buzzer is also
included for audio warning when activating and
deactivating the board.

The KK2.1HC added polarity protection to the
voltage sense header and on-board buzzer. The
voltage sense line has been updated for better
accuracy. The Hard case is clearly labeled, making
installation and connections a snap.

If you're new to multi-rotor flight or have been
unsure about how to setup a KK board then the
KK2.1HC was built for you. The 6 Pin USBasp AVR
programming interface ensures future software
updates will be quick and easy.

(Custom Mix via the "Mixer Editor" option)

The Mixer Editor allows you to adjust where and
how much signal the motors receive from stick
input and sensors. This allows you to create any
configuration possible with up to 8 motors or
servos.

* Note: The programmer does NOT need to remain
plugged in for the KK to operate, Simply plug in,
program, unplug then fly

** Note: It is all ways recommended to update to
the latest software version as part of your
initial setup.(This is different than v1. 6 for
KK2.0) 

*** Note: The KK2.1HC uses the same firmware as
the KK2.1~2.1.5
