CVDs with taper-fit axles?

[Coelacanth]

With my OptiMutt project, I have a few nice sets of Sees & JPS aluminum wheels that fit the original Optima series' axles. These axles were all taper-fit, and the Sees wheels just bolt right onto the stock axles, as they're tapered on the inside of the wheels. The problem is, I'm using modern CVDs, all of which I have are straight 5mm axles with cross-pins.

I could make a hybrid CVD to get those nice JPS/Sees wheels to fit, if I could find the axle ends with tapers instead of cross-pin holes, and install them on the CVD bones. I have the bones with the perfect lengths already so it's just the axles I need to swap.

Does anyone know of any axles with tapers that can be used with CVD bones? I've attached a pic of Kyosho CVDs, the cups are on the bone ends, not the axle ends. So I'd be looking for axles with the ball ends, not cup ends. Anyone have any ideas?

MIP made CVDs for the Kyosho Spider series, which have the proper axles, but you'll have to find an alternate dogbone part, as I'm not sure they are compatible with the modern Kyosho bones. They were sold as a Kyosho Teammm part.

if MIP made axles, then you should be able to use any bone MIP makes that is the right length, and is of course the right half. MIP uses the same size CVD across their product line, so you could use a traxxas bone on a losi axle, for instance.

Thanks guys, looks like I'll be doing more research tomorrow following those leads.

Some part numbers to help you:

GP-10 MIP CVDs: Kyosho Team 57453 (might fit Optima)
Spider GP MIP CVDs: Kyosho Team 57442 (will need new bones)

just a dumb question though.

Wouldn't it be easier to mod the wheels to fit a pin drive?

It might be that I have several hobbytype machine shops locally that would do that cheaply for me that it seems to be an easy alternative. But I also realize the 'thrill of the hunt' so that might be what you are after also...

Nope, I don't think that would be very simple--or even possible. There's a very thin standoff on the inside that would need to be machined down quite a lot to make it work with cross-pins; furthermore, there's not enough material, diameter-wise, to machine it so that the pin will be retained. I'm not sure how to explain it but you'd need to cut out a rectangular depression to retain a pin, not just a slot like the RC10/Losi wheels have. I could show pics later but you'll see there's not enough aluminum on the inside of the wheel to do that.

Thanks for the part numbers, EvoRevo...I had a half-hour search through eBay last night and turned up nothing with keyword searches. Practically every single MIP axle & CVD I saw had 5mm straight axles with 4mm threaded ends, almost none used tapered axles and the few that did had a totally different taper than the old Kyoshos used.

Here is an older list from MIP that may help.

Aaron, any chance you could upload that image to the forum? My work blocks Photobucket and a bunch of other image-hosting sites. That would be simply fabulous.

I had no love whatsoever scouring the 'Net to find images of those outdated part numbers EvoRevo mentioned...nada on eBay, zilch on the Internet...I don't suppose anyone has those? Without a pic, I have no way of knowing if it might work or not.

[aip47-2008]

Well lets try this then.

[Coelacanth]

That's great, Aaron. It gives me a whole lot more to search for. I ended up building a hybrid CVD set for CYANide using info from an old MIP catalog like that, and parts I found on eBay.
