Trim Speed Controller Addresses Run-Away And Failure Issues

TCW Technologies Says It Offers A Safe Trim Option

By Gene Yarbrough

Safety-Trim is an electronic speed control system for standard electric trim servos found on many homebuilt aircraft.  It replaces other speed controllers and relay modules with an electronic solution that resolves issues such as run-away trim and failure to operate conditions. Safety-Trim greatly simplifies trim switch wiring, especially when installing pilot and co-pilot switches. Safety-Trim is available with 2 Speed operation, allowing automatic high and low speed trim actuation.

Among the features and benefits claimed by TCW Technologies for Safety-Trim are an electronic servo controller with speed control run-away protection, time limited operation prevents trim servo run-away conditions, servo travel limited to 3 seconds per trim switch actuation, and a reverse function switch which allows the pilot to recover from a stuck or failed trim switch.

The switch also eliminates many other components, no extra relay decks or speed controllers needed, Very simple wiring, no extra parts needed for pilot and co-pilot trim switches. 

Designed for standard electric trim servos, such as the Ray Allen T2 & T3 series, it is short circuit proof and reverse polarity protected. One and two axis models are available, as well as user adjustable 1 speed and 2 speed models. The device is for Experimental aircraft only, it is NOT TSO'd.
