Program description - Pro trim | Helicopter models
Pro trim
Pitch, throttle, tail-rotor, and C1 curve trimming
This option is available on both transmit-
ter types.
The
mc-16 HoTT and mc-20 HoTT
transmitter’s software has an integrated
function for additional trimming of 6-point curves; in
Heli programs »Channel 1 curve« page 137, and
»Helicopter mixer« page 184. These are intended
for “Pitch”, “C1 Throttle” and “C1 Tail” curves.
This feature, named »Pro trim« because of its func-
tional similarity to the Profi-Trim module for the mc-24
but only available on that transmitter as a re trofit op-
tion. Select this feature from the multi-function menu
with the selection keys of the left or right four-way
button …

To assign a transmitter control, use the selection keys
to navigate to the desired line then tap briefly on the
centre SET key of the right four-way button …
