The Trim Wheel is identical as used in the TRC472 panel and is a smaller version of the original trim wheel as used in a.o. the Cessna 172 Skyhawk.
Although smaller, the working is very close to the original trim wheel. 5 turns moves the pointer from "Nose Up" to "Nose Down", just like in a real Cessna 172.
As the electronics have a dipswitch to set the identity, up to 2 Trimwheels can be used in a single setup (for example one for elevator trim and the other for rudder trim).
The Trim Wheel is produced from high quality, heavy massive plastic and a high quality 5-turn potentiometer is used to read the position information available from the USB controller.
The mounting holes are positioned to fit the Trim Wheel in the TRC472 panel.
The Trim Wheel comes with the necessary screws for mounting.
