The first product line being introduced by 2icrc is designed to be used as a Co-op Piloting System that allows two pilots to share full or partial control of the same vehicle. This device takes the "Buddy Box" style of flying to the next level by eliminating the "trainer cord" and much much more.... The XPO transcends well beyond the concept of a Wireless Buddy Box and introduces Co-op Training, Co-op Piloting, Co-op Competitions and Control Redundancy to the R/C Hobby. XPO's cross brandname capability gives the hobbyist unprecedented versatility.
