These little 1/12 scale Tamiya kits are fun, with the Monkey (which Ive built and shared here) and Dax being much less complex than something larger and not aircooled.
As for the Dax, this isnt something currently sold in the US market, likely because it would detract too many sales from the Monkey, Grom (both which shares its underpinnings), and the Trail 125.
Looking forward to seeing your experience with this build.
