Trigger B options are any physical switch or any virtual switch (more on those later). Both A and B
switches can control either count up or count down.
You can also enable voice announcements of time. 'Minute call' will say the time every full minute,
while 'Beep countdown' will give announcements several more times during the last minute. These
can be activated on page 1/11 of the Radio Setup menu.
T-Trim (Throttle Trim)
This is a useful feature for fuel-powered models. When activated (1) the centre detent for the throttle
trim is removed and (2) throttle trim affects only the “low” side of the throttle range. That means you
can use the trim for setting idle while full throttle remains unchanged. When not activated, throttle
trim has no effect.
6. T-Expo
Another throttle-related function, this one makes the throttle stick expo setting go from zero to full
instead of having a centre point like expo on all the others.
Trim Inc (Trim increments)
This setting determines how the active trims behave.
1. Exp – Exponential – trims are fine near the centre and get coarser further out.
2. ExFine – Extra fine – 1 trim step per click.
3. Fine – 2 steps per click.
4. Medium – 4 steps per click.
5. Coarse – 8 steps per click.
Adjusting the trims produces a series of tones that rise in pitch as trim increases in either
direction. The center point of the trim range is signaled by a haptic buzz.
Trim Switch (“InstaTrim”)
When this switch is activated, the current position of the sticks is copied to the subtrim settings
(Limits page). Choose a switch that is easily reached but unlikely to be flipped accidentally (e.g.,
RUD). The function is triggered by moving the switch from its default position. To trigger it again,
the switch must first be moved back to its default position.
This function is very useful for first flights, as it avoids the need to take your hands off the stick to
press the trim buttons. Simply hold the plane level with the sticks and flick the selected Trim
Switch. Immediately centre the sticks and the plane is trimmed. Fine trimming can still be done
with the trim buttons.
