I just dug up some info that the total length of Optima and Rocky dogbones & axle shafts is the same: about 68mm.

This old Korean page lists a W-5062 for Optima, Rocky & Turbo Rocky, I don't see any of the weird Asian characters but I see "fireboy125", a well-known Kyosho seller on eBay. So, more evidence that Rocky & Optima specs for CVDs would be almost the same.

EDIT: I think your chances of finding W5062 gold universals is next-to-none. Evidently they're very rare. Fortunately, either W5061's or LA245's should work fine, the latter would require a set of 12mm hexes with cross-pins to replace the stock hexes, as I showed previously.

If the dogbone length is the same, then the axles must be different. I don't know why Kyosho would make 2 identical parts with different part numbers.

W5061 - Optima/Optima Mid/Ultima series
W5062 - Rocky/Raider

This is according to the Tower Hobbies catalog from 1989.

I know, but one unit is a gold-plated item. Why would they make a completely separate item and then plate it? From my research I believe the Rocky axle shafts are slightly longer. How much "slightly" is, I don't know--but the dogbones are the exact same lengths. I wonder if we'll ever resolve this, because I doubt anybody here owns a set of W5062's. If someone does, do us a favor and measure the total length, from the outer cross-pin to end of the axle threads. I'll post later this afternoon with my full measurement of the LA245's.

I past-up a set of NIP W5062 for $45, wish I didn't. I'll give this thread a few days to see if anyone here know for sure, then I'll purchase a set and see if they work.

[esaresky75]

I see a difference...

[Coelacanth]

The axle shafts seem a bit longer with the 5062's, but without actual measurements, it's hard to tell exactly. The narrower part beyond the threads and before the axle widens, is a bit longer, to my eyes.

The 5062 is the same length as the 5061, but gold plated, and a little beefier. I recently compared them side by side, and it is noticeably more robust. If you are looking for a slightly longer option, the 5063 looks identicle to the 5061, but is a few mm longer. -Jeff

That's exactly what I see.

That said, if it's as small a difference as it seems (2 or 3mm), it's probably nothing that a few shims couldn't fix. Of course, who among us is going to track down W5062's anyway?

Now that it appears you've scored some W5062's, it would be greatly appreciated if you could take some measurements to update this thread.

What is the total length, from cross-pin to the end of the axle threads? What is the length of the bone, from cross-pin to pin-hole?

Thanks and congrats on scoring a set of those...those seem very rare!

[esaresky75]

Here are the dimensions of the ever elusive W5062. Dont mock my 5 minute sketch! I did not include the length of the tapered part of the axle.

[Coelacanth]

Awesome, thank you for that. I'd still like to know the total length--from the left side of your diagram (the cross-pin) to the end of the 4mm axle. That's probably the most important spec.

[esaresky75]

I'll measure tomorrow for sure but I would guess the taper is 4mm in length, so ~95.25mm

BTW, I checked last week, there are still available but the hobby shop is a PIA. They will only do a direct deposit, no PayPal or Western Union. Have you ever done a International money transfer....it costs half of what the seller wants.

[esaresky75]

How about that for a educated guess. The actual measurement is 94.5mm from the end of the threads to the center of the pin. Now give me measurements of the W5061 and the CRD style.
