Servo tester+AA battery holder

Used to test my servos. Works as advertised and does what I need it to do. Easy to use

There are so useful if you are unsure about your servos. To be honest, I know the actual cost of these PCB, but it was worth a little mark up to have this. Notable that actually running 3 simultaneous 9g servos will overload the power intake and make the device reset. However, it's made tests way easier. Recommended.

After a few tests, the controller stopped working. Update: The vendor was very nice in his communication and refunded the order amount.

Terrible, burnt on first try. Do not buy!

I plugged the servo in first. I plugged the receptacle in horizontally on the top of the three plug prongs. I plugged it in with the brass pins pointing up. Then I plugged in the hot wire to the single row on the top two barbs with the brass tabs pointing down. Then the three blue lights flicker for about 2 seconds and then it just changes to one blue light on all the time, after which you can control your servo with the knob.

Replaced part

It's nice tool to have to check the servo on planes or building new planes to center them and check that they're functioning right before installing.

I needed a battery holder to test out a fan I'm installing on my Traxxas udr aluminum chassis. The servo tester is one of the cheapest things I've seen. I don't need it but just a heads up to someone that buys it for the servo tester it's not worth it.

Works well

Fantastic little tester just make sure you get the AA batter pack for testing if you don't have one but it works like a charm, manual turn, neutral for stillness and auto back and forth on the select, all you need

Works as should but not great case only film of plastic

Deliver on time and works

Came broke
