Review by G Nicholas Gaetanos
Great little tool for setting up control surfaces before you have receiver setup. Also lets you drive motor during initial setup. LED light is little bright. (Posted on 2/20/2014)
Review by brian quinn
handy little servo tester, works as described. the "mode" button is flush mount, did not see it right away. 4.8-6v input and 3x servo outputs. all 3 output whatever mode is selected. (Posted on 8/1/2013)
