Orangemazda’s sneak peek WOIN Ultima

[orangemazda]

I’m too excited to keep it under wraps since today I finely got the transmission to work properly. Here it is so far:

Sweet slipper setup and 48-pitch gears!

And here’s the chassis and arms I’ll be using:

Also, I figured I’d post it now since, by the time I finish it, Kyosho will have re-released the Ultima and it will probably have a slipper clutch in it. I wanted to debut mine first. Lol!

[Mr. ED]

sweet! how did you get the re-re optima internals into the original ultima gearbox?

Any rumours about an ctual re-release yet?

[GoMachV]

Rumors yes....from a very good source that has since passed

[orangemazda]

It took a lot of fiddling. The most difficult part was that the fact that the Ultima case takes 8x14x4 bearings and the re-release Optima takes 10x15x4 bearings. My first thought was to have the diff halves milled down. Then I was looking around on the AVID website and found 10x15x4 flanged bearings. So I drilled out the case and loaded the new bearings from the inside. I also had to make some upper shaft shims. I was able to find some perfect aluminum shaft at the hardware store that has a 5mm ID. I had to shorten a couple of the Optima shims as well. Open up the upper bearing holes so that the spacer/shims ride on the actual bearings, etc. Quite a bit of fiddling and fitting but I’m happy with how it came out.

After turkey day today I had some time to do some more tinkering:

[Mr. ED]

You can't appreciate enough how much easier this got with todays battery sizes. The things I had to do to fit "full" size stick packs inthere ...

High cool factor on this build!
We´re ready for an update

[orangemazda]

Soon. Gomachv is designing some cool shock towers and upper plate for me.

You're going to have to move the tower a good 5mm forward, and the shocks behind it if you're serious about using those rear arms.

[orangemazda]

Perhaps. I was inspired with an idea after looking at these freakishly long RPM arm shock mounts. We’ll see how it plays out. I’m not a huge fan of shocks behind shock towers on vintage cars but if that’s what it takes, I’ll burn that bridge when I get there.

Also Mr. ED, i’ll probably message you and have a conversation about Kyosho CVD’s and various Kyosho rear hubs again. I’m really inspired by your car and SHY’s car too.

are those bandit rpm rear arms?

[jwscab]

Judging from the hub carriers, they are monster truck conversion pieces that we're meant to use with yokomo universals for Rc10.

[Mr. ED]

Who made that conversion? Is there a thread on one of these on the forum?
