Go 1/8 scale for bashing unless you want a crawler just my opinion. The sct's are real hard on lipos when it comes to bashing especially the Tekno. I have a Tekno sct410 and schumacher buggy and I have bashed an 1/8 scale buggy so this is coming from my experience. And for playing in the dirt pick up a set of badlands and let the grass know how much you hate it.
