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.
SAFETY-TRIM HD IS NOW AVAILABLE. FOR SERVOS UP TO 10 AMPS!
