Features
- The wheel drawn through its slot: a ribbed rim with round knobs that crowd and foreshorten as they curve away, shaded where it enters the pedestal
- The wheel turns as you drag it and settles at the simulator's trim (4 degrees of wheel per 1 % of trim)
- Indicator slot with nine marks and a white tab showing the simulator's elevator trim (nose up: down the slot)
- TAKE ▶ OFF mark a little nose-up of neutral
- NOSE DOWN / NOSE UP placards with arrows and the ELEVATOR TRIM label
- A tick sound and a haptic click for every 1 % of trim sent
- The indicator tab hides when the simulator sends no trim value; the wheel still works
- At night the plate takes the panel's flood light
On the iPad
- Drag the wheel down for nose up, up for nose down: every 5 design pixels of drag sends 1 % of trim
Settings
- Size: 1 × 1 or Standing 1 × 2 (picker variant)

Simulator data
What the Hub reads from the simulator for this instrument, and what the instrument sends back. Names are the simulators' own: MSFS SimVars and events, X-Plane datarefs and commands.
Reads
| Value | MSFS | X-Plane |
|---|---|---|
| Elevator trim, -1..1, + nose up | ELEVATOR TRIM PCT (percent over 100) | sim/cockpit2/controls/elevator_trim |
Sends
| When you… | MSFS | X-Plane |
|---|---|---|
| Dragging the wheel: +1 per 1 % nose up (drag down), -1 per 1 % nose down (drag up) | ELEVATOR_TRIM_SET | sim/cockpit2/controls/elevator_trim |
Add-on aircraft with their own systems may use other variables; the Hub reads the standard ones.
Changes
The instrument's version counts what its faces share (the case, the mechanism, the data, the sounds); a face's own version counts that face alone.
