Spektrum AR6210 2.4G 6-channel DSM2/DSMX Ultralite Receiver with Satellite (bulk discount, no packaging) The AR6210 DSMX® 6-channel receiver is a great solution for all model aircraft requiring full range up to six channels. This DuaLink® receiver simultaneously gathers information from two receivers that is processed by patent pending Spektrum™ software that combines it to form the most vivid picture of an RF signal. This dual-path redundancy, plus the fact each of the two receivers is located in a slightly different location, exposes each to a different RF environment and creates a bulletproof RF link in all conditions. Note: The AR6210 receiver is not compatible with the original DX6 park flyer radio system. The AR6210 receiver is compatible with all radios that support DSM2®/DSMX technology.
