Futaba S.Bus2 Programmable HV Servos

Now R/C cars and trucks can enjoy the many advantages of Futaba S.Bus2 servo technology! Because they’re brushless, these servos last much longer than brushed servos, with much faster response times.

They stand up to jolts and vibration better, for smoother operation — and programmable capability allows drivers to fine-tune performance to meet specific applications.
