This is the Kyosho MR-03EVO W-MM 12,000kV Chassis Set. The current MINI-Z has a built in receiver, servo and ESC in one controlled PCB unit. But the new MR-03EVO Chassis Set has a separate receiver unit. By purchasing and installing an optional receiver unit depending on your preferred transmitter, it allows for using a Kyosho (KT-18/EX-6/EX-6R/KT-531P/KT-432PT), KO Propo (EX-2/EX-RR) or Futaba (T7PX/T7XC) transmitters. It will also be available for use with Sanwa transmitters in future. Further, by installing a new CPU which controls servo function only, it improves the internal feedback of positioning control which is 11.2 times faster than the existing VE PRO models.

The newly developed control program provides the best ever steering feeling in MINI-Z history. The ESC has also improved the response speed to a maximum of 100 times faster than existing VE PRO models. The included KYOSHO SPEED HOUSE XSPEED 120 (12000KV) brushless motor features a one-piece aluminum case that provides efficient heat dissipation for superior cooling. Unlike previous chassis sets, you can change to the brushed motor mode though the I.C.S manager to install an optional brushed motor. The I.C.S manager also allows more precise setting adjustments to be made. New advanced performance features in the MR-03EVO take the MINI-Z racing experience to the next level!
