The SR3100 receiver is specifically designed to take full advantage of the advanced DSM2® spread spectrum protocol that the Spektrum brand uses in the DX3R racing system. This means it will provide the fastest response of any spread spectrum receiver, in addition to glitch-free performance. And it gives you all these advantages in a package that is small enough to fit on a 1/18-scale chassis with ease.
