Plugging your speed controller and battery into this programming card allows you to program the ESC according to a series of LED indicators.
It has buttons at the bottom so you can navigate through the menu and select the feature you want, then change it. It's very simple to use and is much easier than listening to jingles or a series of beeps.
This item is an excellent addition to your flight kit, and lets you quickly change the BESCs settings in the field in a much shorter time and with greater assurance that what you have changed is correct and saved into the ESC.
No more black magic throttle stick programming! Throw away the manual, you wont need it anymore!
Compatible with all Hobbywing, Thunderpower, Turnigy and OEMRC Sentilon speed controllers.
