The existing MINI-Z has installed receiver, servo and ESC by one controlled PCB unit. But the MR-03EVO N-MM2 4100KV chassis set has a separate receiver unit. By installing a receiver unit depending on your transmitter, it allows for using Kyosho (KT-18/EX-6/EX-6R/KT-531P/KT-432PT), KO Propo (EX-2/EX-RR) and Futaba (T7PX/T7XC/T4PM) transmitters.

Further, by installing a CPU which controls servo function only, it improved internal feedback of positioning control which is 11.2 times faster than existing VE PRO models. The control program provides the best ever steering feeling in MINI-Z history. The ESC also improves the response speed a maximum of 100 times faster than existing VE PRO models.

The KYOSHO SPEED HOUSE XSPEED 41 (4100KV) brushless motor features easy-to-drive power characteristics and longer runtime. 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.
