Tamiya Hex Questions for wheels

[mikedealer]

does anyone know what size hex these are?

are the hexes the same size as the ultima/optima? or different?

[civilguy]

Those are 12mm hex.
You'll need to have a Kyosho person chime in on whether or not those buggies had 12mm or not.

[mikedealer]

awesome yes, kyoshos are 12mm hex also, thank you!

Mike, these adapters will not fit on an ultima axle. They are for the frog axles which I think is 6 mm diameter. Beside that the threaded part of an ultima axle will be inside of the adapter leaving nothing to thread the nut on.

If you want wider axles and hexes you can use (kose?) tlt-1 option parts: as I did for my ghostrider project, or the TGX wide axles with about 10mm thick plastic hexes

actually, wanted these for a frog so i can use same rims/tires on my ultima lol

[Mr. ED]

ah , right. Then those are exactly what you need, but much cheaper are the hpi truck wheel adapators. With a small modification, the adaptors for putting hpi wheels on a monsterbeetle will do the exact same as these tamiya parts.

What ere you going to use on the front of the frog? Can you put the steeringknuckles of the ultima rb5 on the frog monsterbeetle style?
(you could also try prying 8x5 bearings into asso front wheels I think)

I believe RCmushroom.com has the same part for less $.
