Thanks for reply, guys.

ball diff. is great, but it takes too much to get both front and rear.

re-pro body, dampers etc., are all available.

If I were you, I'd clean it up and re-build it from scratch.

Is the differential a ball diff.?
If so, what brand is that?

Le Mans 490 (brushed motor)

Nice mod.

IMO there is one more advantage of twin belt.
Lower the CG by moving motor and lipo into a lower position.

Whether MID comes first or not, Kyosho has to do the re-re business quick because we are getting older and older.

Those who know Ultima or MID series are normally 40 years old or above.

Looks cool...I'm interested to see how you re-mount the gearbox and outer gears. This was a previous version. The counter gears and the gearbox are in a CNC factory, that's why I can't take a picture at this moment. https://scontent-tpe1-1.xx.fbcdn.net/t31.0-8/13235366_1260709157302484_633685191668...

It's about Kyosho Optima with mid motor conversion.

I'll upload some pictures later on.

IMO we're more likely to see re-re MID series before re-re Ultima.

Because the suspension, differentials and stabilizers(plastic parts) are interchangeable with Optima 2016 , those toolings can be shared.

I second your idea. Love to see the Lemans series coming back.

The FX-R is a great buggy ESC. It was never designed for crawlers, it's just useful for them due to its small size. It is a lower budget version of the FX-R Pro which has an unlimited rating, the FX-R uses the same control board, but less FETs. The FX-R will handle brushed motors down to 12 turns, ...

Given the Tekin is made for rock crawlers, I'd doubt it could handle a faster buggy motor. They're designed for 30-35T motors, you're likely running half that, meaning much more power. The Tekin doesn't even have a heat sink. You'll likely pay the extra money, and blow the esc. Thanks for your comm...

Easy response to that is don't use a "powerful" brushless setup. Most any of these vintage ride can handle a mild 17.5 and I know surely they can all handle a 21.5 or 25.5 setup. I have Hobbywing Justocks and eco power 17.5's in most of my cars. Blinky is the key cause I do feel the boost...
