Yokomo Super Dog Fighter

Post by GWXP »

Hi all,

Back with another few pics with some identity issues.

I'm guessing late 80's and the mechanical speed control is something I've never seen.

Normal for wiring to run between the belt?

Front shock tower is different from what I've seen?

Anything else I've missed?

Does that have a vintage Le Mans motor in it?

well that's certainly one way to do it.

the car was not offered with any type of speed control to my knowledge, so someone added it. I don't recognize it but it could be a popular model's speed controller of the time. typically one would install an esc (electronic) vs the hassle of the mechanical setup.

the wiring is supposed to route over the belt with a small looped bracket that is part of the belt tensioner assembly.

the front shock tower is backed up with some home made bracketry.

it looks like a possible kyosho front bumper installed under the factory bumper.

it's a nice time capsule there.

Front bumper would be Hirobo and MSC would be Aristo-Craft Hitec
Time to break out brush and soap :-)

Yes it does, I haven't seen this one yet but I believe it's a 360

Does the stick pack battery only go on one side then from a guess? Doesn't use the split cells?

Given bumper isn't standard issue then it would go for sure

To get the MSC working again? or just in general needs a good clean as it's not been touched since 1989?

Chassis layout is meant for saddle pack cells. 3+3 or 2+4.
The "body mounts" are actually the mounts for the battery braces.

Soap and brush was meant in generally. To get the MSC going, rub it with contact cleaner and re-lube with contact grease. If the contact points are corroded, clean them with "fine" gritt sanding paper (240 and up) and re-lube.
If it was mine, I´d ditch the MSC and find a cheap period correct ESC. It´s one of the best 4wd buggies from that period and is well worth the extra cost (20-30 usd) for an ESC.

agreed. you have the manual, so strip it down, soap and water as necessary, and rebuild everything as per the manual. Get yourself a novak or tekin from ebay that works, and find the missing pieces, which shouldn't be too bad. As I mentioned, the front bumper is on there, just underneath(on top?) of the hirobo(thanks for the correction) bumper.

you can either run individual cells nicd or nimh, or convert to run lipo saddle packs.

one note about build per the manual,; the stock shocks are pretty crappy. for light running, it's not an issue unless they end up leaking badly. otherwise, associated shocks were the standard substitution back in the day.

the cool thing is you have technically a C4 super dog fighter. Taken from the yokomo timeline thread:

Late 1987: Yokomo YZ870C Super Dog Fighter
For me the first true competition 4WD car released by Yokomo although I am sure there are others that would disagree (hint: YZ-834B). Set the standard (along with the Schumacher Cat) for the future development of 4WD Competition Racers in terms of belt drive drive train and chassis/battery layout set-up. Not widely released in the U.S.A but was imported in very small numbers as the Yokomo C4.

1988: Yokomo YZ10 (U.S. release version ofthe YZ870C)
Identical to the YZ870C but with some cosmetic changes such as white rims (as opposed to pink rims on the YZ-870C) and a more box-shaped Protech 4 Body to make the car more appealing to the U.S. market. Also minor running changes such as slightly (and I stress slightly) improved shock absorbers. Sold under the Team Associated banner.
