Servo Motor Tester Kit | 180 Degree 9g Servo Motor + RC Servo Tester Controller + 6V Battery Holder

I took some hobby grade plywood and made a base, then hot glued the tester, and the battery tray to it. Then I soldered in a switch from here on Amazon B07G17HWW8 so the batteries would not go dead as the tester has no off switch. I put a drop of hot glue on the power plug where it connects to the tester to make sure it wouldnt come loose. Then I added two (could take three) servo extensions B01LA9YDEI so that I can sit the tester in a stable spot on the plane for servo testing. It works great! Well worth the bucks. Ever hear a grindy crappy sounding servo at the field? This guy will find it for you easily, without needing anything extra. BONUS: with two servos connected it will move each in the opposite direction. Very handy for checking two servos (or three even) at the same time.

easy to use

I tested several 9g servo motors and like the simplicity of this kit which allows me to test without having an RC receiver in the mix. The only problem I ran into is the very soft and fragile plastic cover around the circuit board which is open on two sides and could let moisture and contaminants into the circuit board.

Works for all servo testing, and even on most esc I've used. Makes kit building much easier and tuning setups a breeze.

The wire broke and the servo wouldnt work

My 10 yo grandson connected it all up and got it working quickly. He is now building little projects around it.Great fun.We will be buying more.

The battery sucked so bad that it burned a hole in the plastic. Otherwise the motor is fine but the controller is very buggy it breaks time to time and it just gives out sometimes.

This little gadget is quite handy, a ready means to check a new or used servo before putting it in place. For a little money, one can save a lot of trouble. Testing a servo before installing it helps avoid the need to disassemble an RC model to remove and replace a servo hidden in a tight spot. The tester itself comes ready to go once one pops in four readily-available AA batteries. Certainly this is easier than hooking up an ESC, a battery, a receiver, and then testing a servo through a transmitter.
