The R7003SB was primarily developed for models using Futaba S.Bus system such as helicopters/drones but it equally suitable for fixed wing models using this system, or other models using only 3 channels. This tiny full range FASSTest receiver weighs in at only 7.2g and has a moulded plastic case for added durability. The S.Bus system allows for a simpler setup on complex/perfiormance models and has full support for S-Bus and S-Bus2 servos. The R7008SB is high voltage capable, meaning it can take power from sources such as 2S li-po batteries (3.7 - 7.4V supply). As supplied the R7003SB receiver includes integral sensors for receiver voltage, signal strength and external voltage, with further separate sensors available seperatly. • FASSTest (18ch & 12ch) • Telemetry with built-in voltage sensor • EXT-VOL external voltage sensor included (0.70V) • PWM allows 3 channels • S.BUS allows 18 channels • Small and lightweight • Moulded plastic case • Dual antenna diversity (coaxial antenna) • Full range operation
