It's a little different than a truggy, which would be the Mammoth ST. It's longer, and uses a large support for the wing that attaches to the chassis.

You might just want to get a Ofna Hyper 7/8 differential and put the Kyosho plastic spur gear on it, so you don't have to deal with hardened pinion gears.
