Also,
if
you
enable
MAVLink
for
output
8
there
will
be
an
option
to
send
RC
signals
over
the
MAVLink
connection.
You
can
find
this
setting
under
“RX
Diversity”
menu
called
“MAVLink
PPM”.
If
this
setting
is
enabled
there
is
no
PPM,
SBUS
connection
required
anymore
between
TBS
CROSSFIRE
and
the
FC.
Note
this
MAVLink
message
(RC_CHANNELS_OVERRIDE)
will
only
send
channel
1
to
8
to
the
FC
even
if
TBS
CROSSFIRE
is
set
to
12
channels.
The
TBS
CROSSFIRE
diversity
receiver
has
a
build
in
MAVLink
engine
which
forwards
messages
like
GPS,
attitude,
current
sensor,
flight
mode,
time,
air
speed
and
more
to
the
BST
bus.
In
case
you
use
the
TBS
CORE
PRO
or
TBS
BLACKBOX
all
required
messages
will
be
forwarded.
The
engine
also
adapt
the
MAVLink
bandwidth
to
make
it
perfectly
fit
the
RF
link
bandwidth.
This
gives
you
the
best
performance
for
both
OSD
on
the
TBS
CORE
PRO
side
and
on
the
telemetry
over
TBS
CROSSFIRE
in
terms
of
latency
and
update
rate.
If
you
run
the
system
with
a
TBS
CORE
PRO
you
can
decide
if
you
want
to
run
the
digital
TBS
current
sensors
or
use
the
current
sensor
information
from
the
FC
for
the
OSD
display.
In
case
of
using
the
current
sensor
from
the
FC
you
need
to
make
a
custom
wire
to
power
the
TBS
CORE
PRO.
This
cable
requires
only
two
leads
out
of
the
default
BST
cable.
+VBATT
goes
to
the
flight
battery
plus
and
GND
goes
to
the
flight
battery
minus.
Make
sure
the
other
leads
do
not
touch
anything
or
short
against
each
other.
Note:
If
you
use
the
TBS
CROSSFIRE
and
the
TBS
BLACKBOX
at
the
same
time,
make
sure
only
the
TBS
CROSSFIRE
is
connected
to
the
FC
by
MAVLink.
It
will
automatically
forward
all
necessary
information
to
all
other
devices
connected
by
BST
to
the
TBS
CROSSFIRE.
