PRECISION CONTROL THAT #39;S TERRAIN TOUGH The Spektrum DX5 Rugged 5-channel surface system redefines radio control with unmatched innovation in durability that no off-roader, basher or boater will want to be without. The result is precision control, convenience, and #34;rugged #34; versatility. UNMATCHED DURABILITY Starting with a chassis based on a superb Spektrum ergonomic design, we were inspired by the punishment capability of cordless power tools, and translated their die-hard engineering to the specific needs of the RC driver. The result is a shock-absorbing rubberized bumper design that surrounds the transmitter chassis to form a level of protection never offered before on a surface transmitter. Unmatched Durability AGGRESSIVE STYLING The DX5 Rugged stands out as a transmitter platform that means business handling the wildest terrain, the toughest conditions and fierce competition without any worry. That #39;s why we designed durability hand-n-hand with convenience. A built-in side compartment offers tool storage, and two lanyard mounts (one rubber, one molded into the chassis) are supplied so you can be hands-free in an instant. Inspired Ergonomics INSPIRED ERGONOMICS The ergonomically-recognized DX5 Pro and DX5C transmitters paved the way in giving the DX5 Rugged a feel any driver could appreciate. Overall low weight offers all-day driving with minimal fatigue, while the non-slip rubber grip and its trigger-throttle action offer a precision experience that feels natural.
