Locked diff's or not??

[snydas1987]

I'm wondering if its best to have locked diff centres in my 1/8 truggy foff build? If so what's the best way to lock the diff's. Probably be using a hpi trophy truggy or similar for the rolling chassis.
Thanks guys

I'm totally new to this, but regular cars sure can crawl further with a locked diff (at least rear) than with an open one. Same with rc I guess.
