Program description - Profi trim | Helicopter models
Profi trim
Pitch, throttle, tail-rotor, and C1 curve trimming
This option is available as standard on
both transmitter 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 141, and
»Helicopter mixer« page 188. These are intended
for “Pitch”, “C1  Throttle” and “C1  Tail” curves.
This feature, named »Profi trim« because of its
functional similarity to the Profi-Trim module for the
mc-24 but only available on that transmitter as a re-
trofit option. Select this feature from the multi-function
menu with the selection keys of the left or right four-
way button …
