This is the Nikko counterpart of the Radioshack Golden Arrow, it's called the Nikko f-10 RHINO Frame Buggy. Earlier I mistakenly called this the Bison. It was only after I took it out of it's storage box that I realised the error.
I beleive this to be a worthy counterpart to the Radioshack Golden Arrow buggy. It basically has a similar tub chassis, front trailing arms, and almost identical rear transmission. The onboard electronics on this buggy is different from the Golden arrow.
The f-10 RHINO buggy has a TRUE digital proportional speed contol. You can actually run this thing to a crawl, the Radioshack Golden Arrow is just Full speed forward or full speed reverse. This buggy has four oil filled shocks which gives it a marginally better handling that it's stock version. The OEM Transmission has full ball bearings. The motor in it is a Traxxas Stinger 20 turn motor. The spiked tires gave this buggy the needed bite on semi soft soil and hard packed clay surfaces. Matched to this buggy are original 1980's Tamiya grasshopper/Hornet /Frog - three (3) piece wheels. Front wheel camber (toe in or out) is adjustable and steering arms are made of metal commonly found on the Tamiya frog, Brat & Sand Scorcher series. When I got this back in the early 90's the hobbyshop tech told me that this was his "testbed buggy" that he used as a reference in modfying the RS Golden Arrows he worked on.
