JETI model DUPLEX DC-24 Manual page 86

Advice:
For the maiden flight we recommend using larger trim
steps. After familiarizing yourself with your model's
behavior you can switch to smaller steps for finer
trimming.
Flight-Mode Group (A/B) – if you are using several flight modes and
you want to share trim settings among a few of them just
set one of the groups FA or FB for the particular trim. Each
group has its own settings which are then shared. Note: If
you change from Global to any Flight-Mode Group, the trim
mode in other flight modes than the current one will
become Separate.
Note: If you change a flight mode from Global to either of the
Flight-Mode groups the trim mode for the rest of the
flight modes (except for the one you are currently
editing) will change to Separate.

The rest of the parameters are described below:
1. Value – shows the actual trim rate.
2. Stored – shows the stored value of trim memory function.

3. Mode – here you can specify a basic behavior of the trim:
• Centered mode – by default, the trim affects only the servo
center, the endpoints remain untouched.
Linear – shifts the whole servo travel, including endpoints.
•
• Thro-Low – affects the servo low endpoint and the entire
curve, except for the high endpoint.
Thr-L50% – affects the servo low endpoint and curve below
•
50%. This does not affect the curve above 50%
• Thro-High – affects the servo high endpoint and the entire
curve, except for the low endpoint.
4. Step – indicates, how much the value of trim changes each time
the trim button is pressed.
5. Rate (+,-) – determines maximum limits used for the trim.
In the picture below you can see how various trim modes influence
the servo output (trimmed to ca 50% of range). However, you
cannot use any trim mode at any time:
V-Tail configuration - You can specify the trim mode only for the
elevator function, not for rudder since these functions are linked
together.
Delta/Elevon configuration - You can specify the mode only for
ailerons, not for elevator.
Helicopter using CCPM mix - You can specify the mode only for
pitch function, not for elevator nor roll function.

If you use two or more trims to adjust a single function, the resulting
trim rate equals to a sum of all rates that are participating on this
function. However, the transmitter uses always only a mode defined
for the first trim.
