Thanks for the comments and help lads
I've found a solution that I will start out with:
- TRF201 Axles+Driveshafts (64mm)
- DEX410(R) Hubs+Casterblocks
The car will end up being 240mm-ish, not 245 or 246 like I'd prefer to, but geometry-wise it seems to work fine.
I'm kind of finishing up the design right now... The main things left to do were to optimize the battery tray, make the rear shock tower and finish the electronics install:
It's a bit tight on space if you are not using the top deck, but it is possible, even with the huge Futaba receiver and bulky HobbyKing ESC I will be using.
I hope to have a mockup of the front end on the table soon - Fingers crossed!
