GT Power Servo Teste 3CH Digital Multi Servo Tester RC Aluminum Shell Servo Tester ECS Consistency Speed Controler Checker for RC Helicopter Car Boat

I own about three of these and they work great! Years ago I used to hook up a receiver and go through all the trouble of using my radio to test and center servos- a royal pain to say the list. With this little tester you just plug in a 6 volt power supply and press a button for three modes of servo test: pan the servo by turning a knob, center mode for centering the servo and a mode that runs the servo back in forth automatically. WAY better than the old method I used to use. No more dragging out a radio, hooking up a receiver to test. The only complaint is the LED is BRIGHT!! But, this is easily resolved buy simply placing your finger over it, not a problem worth taking away from the great functionality of this little tester. An absolute must have for any builds. Seller shipped fast. Highly recommended.

I have one of these testers in the cheaper plastic paper wrapped format. That tester is hopefully going to be permanently assimilated into a future project.I wanted to have one on hand though, so I picked this up. As far as function, there's not much to say, it does what it's supposed to do. But the aluminum shell it's enclosed in is a aesthetically pleasing and durability enhancing touch.I actually have dropped this a few feet onto my work bench and it still works fine. Had I dropped my plastic paper wrapped tester, I'm sure I would have at least had a bent connector pin to deal with.So if you just need a servo tester to sit there and see rare usage, save your money and pick up a paper wrapped one, but if you're going to use it constantly and in situations where it might see some physical abuse, this aluminum enclosed one is a good bet.

Works well as a basic servo tester, it has helped me setup a few airplanes already and helps take the stress out of it. Solid value and the metal case really makes it that much better.

Does what it's supposed too but not ideal for high voltage servos such as helicopter tail servos.

3 modes simple and easy to use..if ur building a rc trail truck or crawler this is just a perfect tool to test ur new servo center ur servo or auto or manual sweep the servo horn to ensure everything is on point a great buy..

Pros: You can power your servos to make sure they workCons: It does not accurately center servo. I trusted it and torqued down 7 servos and installed the horns using threadlocker. After plugging into my receiver and powering my transmitter and system, all the servos were off-center. The pain I had to go through to remove all the horns and re-center them manually. Another feature I did not like is that the LED lights are way too bright. I had to cover them with translucent tape.

This is a great little tool. Much smaller than it looks in picture, will fit in palm of my hand. LED's are so bright I put tape over them. The tester works great. I glued a small "on-off" switch to the side of the unit so I could keep batt. pack plugged in and turn device on and off with a switch. Price right.

Metal case is nice and sturdy. Works perfectly with servo testing on my skyhunter build.
