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

Me gustó que es fácil de usar. Para probar servos y otros componentes.

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

This has been very useful for testing out my RC airplane servos. I just wish it had a servo centering feature so that I didn't have to do it with guesswork. I'm glad it came with the AA battery caddy.

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.
