1997 MX-4 Prototype “World Warm-Up Configuration” [REPLICA]

I finally got to build Ruben’s RRP MX-4 97 World Prototype kit, but I could not resist adding a little twist.

Masami secretly tested a slightly different prototype car at the warm-up race that was held a few weeks ahead of the main event.

This car sports different front-end delrin gearbox, front tower, top deck and a very interesting rear tower that mirrored the same toe setting configuration as the front with 3 alloy support holding the toe plate in place. This technical solution was later dropped, but I really like the fact it makes the MX-4 more balanced technically between the front and rear design solutions.

This car was basically the prototype of the prototype of the MX-4 🤣. There is only one original car in existence, the one that Masami drove at the warm-up practice.

Body painted by Zac @ AttackRC in a lighter colour to match the original car paint scheme.

UPDATE May 2026: I have now acquired the real, one-off car that Masami drove. And all I can say is that it is very difficult to tell them apart! See comparative photos at the bottom below.
