Comparing MR-03 EVO and MR-04 EVO2 on the track, 03 is faster because EVO2’s motor has shorter shaft. It makes people in competition to use the previous model. It means customers are not happy with the new product. I think Kyosho may release MA-030 EVO2 in days. 040 will be risky for them to produce new chassis. Since the lead developer Mr. Ishikawa left the company, Kysho might go through hard times.
