This is the Futaba 2.4GHz R604FS 4-Channel Receiver with FASST (Futaba Advanced Spread Spectrum Technology) Technology for use with Futaba 4PK 2.4GHz FASST transmitter or the Futaba 3PK radio with FASST transmitter module systems. Unlike less reliable single antenna receivers, Futaba employs an antenna diversity system-one internal and one external antenna on the R604FS receiver to eliminate dead spots anywhere on the track
The included R604FS receiver features Dual Antenna Diversity (DAD) for reliability and security. Its compact size (1.54 x 1.02 x 0.55 inches) and weight (0.49 ounces) lets you use it in the tightest installations.
