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)
