This is the Kyosho Mini-Z AWD MA-030EVO chassis set (8500kv/DWS included). The separate receiver unit pioneered on the MR-03EVO is now included in the AWD model MA-030EVO, based on the FWD MA-03F chassis. The MINI-Z was originally designed with an integrated receiver, servo and speed controller, however on the MR-030EVO the receiver was designed to be purchased and installed as a separate unit, allowing the model to be used with other makes of transmitters, such as KYOSHO (KT18/EX-6/EX-6R/KT-531P/KT-432PT), KO (EX-2/EX-RR), Futaba (T7PX/T7XC), Flysky (Noble NB4). In addition, the highest AWD series spec MA-020VE PRO included a 3-stage steering servo unit, but the new MA-030EVO includes the even higher spec 5-stage gear type from the MR-03. Also, a special CPU for servo control improves the control speed of positioning feedback, and the updated control program delivers the best steering feel of any AWD model through improved responsiveness and linear response to driver control. The one-piece heatsink and aluminum case on the KYOSHO SPEED HOUSE XSPEED 85 (8500KV) brushless motor keeps it cool for optimal performance.
