This category now contains only items that are carried in the model. To find programmers and servo testers (bench or field tools) go to Tools sub category Servo Tester/Programmers.
Great device that warns you of trouble with your model. Beeps when it detects low or no TX signal, when voltage dips below 4.2 volts and will shriek if you lose the model and shut off the TX. Helps your favorite model "Be Found". Plugs into extra channel or use as a short extension between a servo and your RX. Comes with universal connector. Use only for PPM Systems (not for PCM).
Provides signal automatically when interference or no signal is received. Example, connect between throttle and receiver and if interference is received it will cause the throttle to go to full idle. Fail safe signal is adjustable.
Spedifications:
7g weight, 40mm x 21 x 8.5. Power consumption 2.3ma(4.8v) or 3.8ma(6.0v). Operates 4.8-6.0v. One end plugs into servo and other plugs into receiver. Direction sheet included. Comes with universal connector.
Universal Y w/ Digital reverser (fits Futaba/Hitec/JR/Airt. Z) for 4.8v - 6.0v applications.
This Reversing Y-Adapter is designed for giant scale, glider, pattern, or sport planes with split-elevators, split-flaps, or twin-engines. This Y-Adapter will reverse one servo and keep the other servo straight.
Both models allow the servo speed to be adjusted, 2 to 10+ seconds of travel in either direction with no loss of servo torque. Go-Slo III units are great for precise operation of Flaps, Gear etc. The receiver cable is now a heavy 22 gauge for better power delivery to one, two or three servos. Go-Slo III's are compatible with 4.8 or 6 Volt systems and all proportional servos. The unit is 1.5" x 1.5"x 3/4" and only .9 oz in weight.
The #880 version has two parallel outputs and a third output reversed. Model #881 has three parallel servo outputs. Universal connectors.

Servo Signal Circuits and Reversers
Sometimes a servo needs its signal changed rather than its position, whether that means reversing travel, converting the signal to another form, or adding a failsafe. This category collects small circuits that alter or condition the servo signal on board the model.
Reversers and Converters
The Servo Y Harness with Reverse Buffer flips a servo's direction and is offered in an Old Airtronics version and a universal version. The Astroflight RCPWM2V converts a standard PWM servo signal into a voltage output for driving other devices.
Programming and Failsafe
The FMA Direct Servo Lab is a bench tool for reading and setting servo behavior, and the GWS FS-2 failsafe unit holds a preset position if the signal is lost. Each addresses a different need, so pick the one that matches the change you are trying to make.
