Profi trim
Pitch, throttle, tail-rotor, and C1 curve trimming
The mc-20 HoTT transmitter's software has an
integrated function for additional trimming of 8-point
curves; in Heli programs »Channel 1 curve« page
131, and »Helicopter mixer« page 176. These are
intended for "Pitch" curves "Channel 1 ¼ Throttle"
and "Channel 1 ¼ Tail. rot.".
This feature, named »Profi trimm« because of its
functional similarity to the Profi -Trim module for the
mc-24 but only available on that transmitter as a
retrofi t option. Select this feature from the multi-
function menu with the selection keys of the left or
right touch pad …
