Cool - thanks mate :D

Out of interest, which 12mm hex drives did you settle on? Axial or HPI?

Cool - I've used the Axial hubs but they're 4mm on one side and 5mm on the other, so they 'skew' a little when you tighten them up, which makes the wheels wobble a bit. Did you find HPI hubs with a constant 4mm bore?

I'm slowly working on the custom delrin centre gears by the way... between building the Optima Pro and other sidelines. I'll keep you up to date :D

Newly made Scorpion hop-ups!

Yesterday a small envelop arrived from US with something I have been looking for some time now to my runner! It contained two custom made wheel hubs so you can us a more modern 2.2” wheels with 12mm hex on your Scorpion runner. I

These adapters are done with a con that fit the Scorpion's odd con and they are 12mm long.

They fit real nice on the CRP CVD’s with no play what so ever and titans good when I mounted the wheel back on.

I did 8 minutes test run on ruff tarmac and grass, at one time I thought I would rip my old diff to pieces. But it holds up and so did the wheel hubs without loosen up. So I gone get me a few sets more of this “Whisler-hubs” tom my next runner built this fall/winter.

He is also making a real nice adjustable motor plate, front arms shaft blocks with set screws to keep the shaft in place and machined cassis rails. His eBay name is dwyz250

Yeah, I grabbed the chassis and motor plate. Pretty nice work isn't it?

The alloy seems very strong!

I would suggest to keep your runs limited to 5 minutes though: to give parts the chance to cool down.
The 240 line would be pushing your luck to my feel.

That’s no problem; those old motors have so week magnets after 25 years. I run a modern LRP 2x17 in my Scorpion with LiPo without problems… But you have to check out your gearbox and adjust any play; otherwise it can end up in tears and a broken gearbox. This you should do anyway. But you are right about the running time; it should be max 5-6 minutes.
