Do you have access to tools? Mill and lathe?

I would go for a nitro conversion, just because of the challenge. Converted nitros rock, as you know.

The 2-speed pinion will not be too hard to make, and in the worst case you could do something with a stock clutchbell.

Yes, 5 or 6S BL setups are insane. But so are the nitro 8th scale onroad cars.

Let me know if I can be of further assistance.
