ok, so the monster im making is just enormously long and crazy, the stock rims and tires just wont do for too long, the hexagonal rim fitting for newbrights, is that standard for rims? do they generally use that? and if anyone knows a bigger sized rim and tire (preferably not too $$$) that would be compatible with an nb axle (width fit etc...) i would appreciate it!

I would also like any leads on replacement rims or ideas thanks

The Newbright hex is not standard. You'll have to epoxy on a set of E-Maxx wheel adapters over the hex, and then epoxy the wheels to the adapters. Then you'll be able to run a 7" - 8" tire. That's I'm going to do eventually.

NICE, thats not hard at all, its a distant project but a definate one

yeah but then you will need bigger motors. and better gearing. but hopoefuly that will be coming soon.

true, im thinking in the future after a hobby swapperoo and flaps new gears or oldstyle gearing
