AUTO TRIM
The "AUTO TRIM" function offers you the possibility
to trim a model easily and quickly, for example during
the first flight or after (bigger) reparations or similar.
During such kind of "first flights" the previous set-
tings of the model performed on the ground may not
fit 100% with the flight requirements, in those cases
you usually need to move the control sticks in order to
correct the model attitude until it flies straight and at
the same time you have to move the trim controls to
obtain the same effect.
Exactly here is the "AUTO TRIM" function useful: after
having reached the required flight attitude through the
control functions 2 ... 4 this function is activated mov-
ing ONCE an intermittent switch previously assigned,
normally a self neutralizing switch. For example the
3-position switch S8, which push function after the
assignation is declared as ON position. (For safety
reasons - see what follows in the "Notice" - is strictly
recommended not to use a switch with a permanent
"ON" position):
As consequence of pushing the switch, the deviation
of the control sticks positions 2 ... 4 from the related
neutral positions are stored as trim value, within max-
imum ±30 %, in about 1 second. At the same time the
control sticks can be released to the normal position,
for example:
Notices
• For safety reasons never use the "AUTO
TRIM" option if you have set "0" as trim step.
• Be sure that the control sticks 2 ... 4 are in
their neutral position while the switch is as-
signed. Otherwise the deviations from the
neutral position will already be stored in the
trim memory as trim values.
• EACH activation of the AUTO TRIM switch
acts cumulatively, that is why for safety rea-
sons is strictly recommended to use the
switch only once and to deactivate it after the
"AUTO TRIM flight" has finished. Otherwise
there is the risk that the "AUTO TRIM" function
might be inadvertently activated.
• Never assign a "normal" position holding
switch to the "AUTO TRIM" function or always
affordable bring the switch to the "OFF" posi-
tion after each AUTO TRIM process. OTHER-
WISE EVERY ACTIVATION OF EVERY OTHER
SWITCH WILL INHIBIT THE FUNCTION OF
THE AUTO TRIM PROCESS.
• The storage of the trim values from the "POS"
line in the "SET" line so as the reset of the
values is performed as described at the begin-
ning of this paragraph.
