Possibly a good find (you're to use a shaft-drive bike motor?).. I didn’t catch the Porsche ratio(?). most BEC guys end up around 3.0:1... maybe all the way up to 4.0 for track use (smaller track).. Ratio, rotation, reverse... I know it’s not at all Locost, but that MX200 addresses them all.. my next build will be my 3rd BEC, and I’m pretty sure I’ll use an Elite rear in it.
You might also look at SXS (off-road cars) front diffs, like a Polaris RZR1K or a CanAm.. I briefly researched them, and had an issue with out-of-range ratios, and they are a bit expensive..they do have a ‘locker‘ function, but it takes a bit of fussing to adapt for BEC use.
Whatever direction you go, an IRS in your BEC will be one of the projects more complex/challenging aspects - especially if you want reverse (and you do want reverse
).. That MX200 is the easy button... I’ve already started saving my pennies for it..
