Bashing, boating or rock crawling, the SR210 receiver can handle the worst nature and the RF environment can throw at it. It’s built around frequency-agile, DSMR™ technology that delivers superb range and response, especially in places where a lot of 2.4GHz systems are in use at once. This unbeatable signal security is complemented by a fuel-proof case and a waterproof Reliakote™ coating that seals internal electronics from the elements and other corrosives, like nitro methane and motor spray.
