… appears then the transmitter does not detect a
memory card in its card slot or the card found can-
not be read.
• If the selection window is empty …

… then the transmitter could not find a suitable
firmware file on the inserted memory card. Check
the contents of the SD card’s “Firmware” directory
on a PC or laptop.
STICK CALIBRATION
If you feel the neutral position of your self-centering
sticks (controls 1 … 4) are not exactly 0 % of their
control travel, then this can be checked and, if neces-
sary, corrected as follows:
Jump to the »Model select« menu and initialize a
free model memory as described on page 79.
Whether the model to be initialized is a winged air-
craft or a helicopter is irrelevant.
Wait for the notices which typically appear in the
transmitter’s base screen following a model change
then jump to the »Servo display« menu, for example
by simultaneously touching the

keys of the left
four-way button WITHOUT any interim changes to
trim settings or other program settings.
If all four of your transmitter’s stick functions are still
self-neutralizing, this display should ideally look like
the one shown below:

Note:
The screen-shot above, and the two which follow,
show the screen of the
mc-20
HoTT transmitter.
The screen of the standard eight-channel
mc-16
HoTT shows correspondingly fewer channels.
Otherwise the graph bars show current setting per-
centages for joystick control functions which are not
self-neutralizing – typically for the “C1” throttle/brake
or throttle/pitch stick. For example, if the throttle/brake
stick is in its “quarter-throttle” position, the display
would appear as shown below:

One after the other, put both sticks into each of their
four possible limit positions without exerting force at
the limit position. In each of these eight possible limit
positions, the – side dependent – indication for exactly
-100 % or +100 % should be displayed. For example,
if transmitter control 2 is at its right limit and the other
three stick functions are in their respective middle
positions then the transmitter’s display should look
like the one shown below:

Regardless of the number of self-neutralizing stick
functions available on your transmitter, if these checks
produce four 0 % results and eight 100 % results then
your transmitter’s sticks are optimally calibrated. You
can terminate this process then, if appropriate, delete
the model memory just created.
Otherwise jump (as described at the outset of the
previous double page) to the “STICK CALIBRATION”
line in the »SECRET MODE« menu then briefly touch
the center
SET key of the right four-way button.

Now position the right stick – without exerting extra
