Ray Allen electric trim systems include a servo, LED position indicator, rocker switch and a clevis/pushrod kit. The heart of the Ray Allen trim system is the servo and they are designed specifically for experimental aircraft. They are small, lightweight, and powerful enough to control trim surfaces on any small aircraft. They will automatically stop when their travel limit is reached and will not travel unless power is switched on by the pilot. Voltage polarity determines direction of travel. Ray Allen servos can be purchased separately for controlling devices that would otherwise require bulky, complicated mechanisms. They are extremely durable and should last the service life of your aircraft. Production samples have been bench tested 50,000 cycles under loaded conditions relating to 244 hours of continuous use or thousands of flight hours.
Ray Allen has 4 different servos available: The T2-7A, T2-10A, T3-12A, and the miniature T4-5. Check the specifications to determine which servo output travel best suits your application.
