I have a couple Losi Mini Crawlers on the way to me, but I have a Mini LST2 sitting here that I thought might make a good crawler....at least for around the house.

I was thinking Hot Glue could be used to "lock" the diffs, and can be removed with some plyers later if needed.

and gear that motor way down....Losi makes down to a 9T pinion....

I think your kinda stuck with the stock A-arms, unless you can find a longer dogbone to go inside as well.
