This handy servo driver allows you to operate your servo or ESC w/o turning on your Tx. Great for workbench set up or field set up when Tx is impounded. This newly updated version has two new features:
• Precise Centering Indicator - All servo drivers let you control ESC. MX8340 also allows you to set precise neutral point for perfect servo setting.
• Servo Cycler - Variable speed cycling for servo testing and break-in.
