We have expanded our line of KAVAN Plus speed controllers with a new 120A piece R-120SB Plus SBEC. It is used to control the RPM of recreational and sport model motors. It has a powerful BEC circuit to power the on-board servos and receiver, and has significantly improved throttle response and power stage control efficiency thanks to DEO control technology. Like the other controllers in the Pro series, it offers a wide range of features that are easily set up with the KAVAN Pro programming card.
