Was going to install on a plane, but didn't want to disassemble it to install. Its made for a 64mm edf but could most likely be scaled up or down for a larger or smaller edf. Will require 2 servos, I'd recommend at least 9g if using a 64mm edf. At full throw it has just over 23 degrees of deflection. While that doesn't sound like much it's more than enough. If you make it please let me know how it works!
