|These Trim Relay Boards allow control of an aircraft’s trim motors from the typical switches found in most stick grips. As the switches in the grips are too small to handle the motor loads and usually do not have the required number of poles, the ‘TRB’ offers a simple, elegant solution that is easy to wire and understand. The boards have a per axis rating of 10A at 12 volts, (24V units are also available).|
Easy to install, does the job. Quicker and tidier than knocking up a DIY relay module. Eliminates the need for a changeover switch to isolate pilot or copilot trim inputs.
