There are tuneable parameters that can make the code run well even in the most demanding situations, although default settings will work - excellently in normal operating environments - The code also supports a beacon functionality, where the ESC will start beeping after a given time of zero throttle. This can be very useful for finding lost crafts. Package Included: 1x Racerstar RS20A V2 20A ESC
