Against my better judgement...
Blessedly, the camera batteries went dead on the third pic. But I thought I'd post one pic of the front.
Is it too heavy? Probably.
Could it be made smaller/thinner? Definitely. I'm even considering doing away with the middle axle/make the sides independent of each other.
But...it should be extra EXTRA durable, and I think I have a partial fix to the problem of lightweight steering hubs and the extra punishment they'll take with no suspension to cushion things. I slightly narrowed the distance between the top and bottom screws, away from the thinnest parts of the hub without actually causing it to bind. So...I get my camber and my caster, it'll take the rubber or the foam tires..now all I need are the ben hur attachments for taking out other cars.
