Customer Reviews

Easy to use and works well Review by Raymond Flach
I accidentally put this review in the ESC and motor combo I bought.
This device came with no instructions. I would like to use it to drive an ESC as I had read it could do that, but without instructions I cannot figure it out. But it works well to center or drive servos. (Posted on 12/13/2018)
Works great for servos and esc Review by Mark Snyder
It work great, just make sure that you plug it in the RIGHT DIRECTION!
And when you plug it the esc plug in your battery on the esc battery lead use the Tester as a rx. (Posted on 3/21/2018)
Outstanding tool Review by Oldensly
This inexpensive servo tester is the cats meow. It works flawlessly and centers the servo positively every time. I like the "window washer feature to break in new servos. (Posted on 8/22/2017)
Sero Tester Review by Kenneth Barclay
I don't know why I didn't have one before! Enables me to center servos while installing the receiver system. Then when the installation is complete centering with the transmitter is a snap. (Posted on 6/11/2017)
