Product Description

Wishiot servo tester+aa battery holder

Features:

Can be easily detected and set the dummy bit server, jitter and median.

Can be connected to two servos or ESC; MCU control, good stability, high accuracy. Turn the knob, steering can be detected.

If you connect the electronic governor (brush or brushless available), you can get rid of the remote control device for manual control, for testing tone Speed ​​or motor performance is very practical, no longer cumbersome connecting the remote control and the receiver. It is equivalent to a "hand Dynamic Receiver "feature, playing rudder knob analog transmitters

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.

Works for testing a servo I guess. There are no markings so it can't be used to center the servo. If that is what you're looking for look elsewhere.

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.

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.

Great value for what it does and works as described

Using with a 9g servo, you have to turn the knob very, very slowly. Even then, it gets stuck on reset while the lights flash.

It lit up and seemed to work until I actually tried it with the servo in my Xane MiG-17. Plugged the same servo into a receiver, and it snapped to center so the servo is not dead. Tried it on a micro RC plane servo. Nothing. I bought this looking for something to set my servos to neutral position before installing the wings on the plane. Wound up not working for the 9G servos that were in the wings for the ailerons. I had tried using different power sources and plugging everything in different orders. The servos were not burned out. Waste of my 8 dollars. The unit is just a PCB with a wax paper casing rather than plastic. Unless you need this for the battery container id advise you stay away. Id put in a request for a refund but its not worth the trouble to ship this e waste back out.

Tested with a simple 90 degree servo briefly. While I was wiring the rest of the circuit I started to smell plastic. I looked at the battery holder and found the negative on one of the battery slots was extremely hot and had melted through! At the time I did not have anything powered on. For the brief moment I tested it seemed to work. This project was for my 3 year old sons room, I hate to think what would have happened if the project was completed and left in his room overnight.
