[scr8p]

I don't think I've seen anyone post it on here yet. But for those not on FB, Moto Obscura ia now offering the parts to make your own 95 Worlds Prototype B2 with the 2.25 stealth.

Nick and I outfitted our B2's with the the parts for the Vintage Clash at Hoosier in March to test the parts before he added them to the website. I also made a video on the RC10Talk YouTube channel if you want to see it a little more in depth.

Here’s my B2 with the proto replica kit that I raced at the Vintage Clash of Champions next to Matt Ledger’s original ‘95 worlds B2 prototype (Matt’s is on the left).

It was really cool to be able to compare it with the real thing, especially since Jason and I developed the replica parts almost entirely from photos.

Do you expect to have the full kits back in stock?

BTW - such a cool kit you guys produced.

I don’t think we’re going to do the full kits anymore. I may make pre-modified transmission cases available for sale, but I’ve been cutting all of the motor plates by hand with an dremel and I think it would be better to leave that to the builder.

i definitely want this kit but with the modded trans case. when will the case be available again? also how much work or how difficult is it to mod the case?

The bottom of the transmission case needs to be narrowed to clear the B2 rear arm mounts, two new bottom mounting screw holes need to be drilled into the case, and a notch needs to be cut into the top front of the case so a tang on the bottom of the transmission brace can interface with one of the 4-40 - 1” socket head screws. I modified my first one with a box cutter, so it’s definitely doable by hand. Now I use a milling attachment on my lathe which is much faster and does a far neater job.

Modified on left, original on right (with areas that need to be trimmed off marked in black). The dots on the modified case needs to be drilled with a #43 (0.089”) or 2.3mm drill bit.
