If you're looking for 4wd and lighter than a 1/8 buggy, theres the HPI mt and mt2. They can be run on a less powerful setup, but are not as durable as a 1/8 buggy/truggy. PM me, I have an older ofna 1/8 buggy roller already converted (spare mmm2200 combo as well) and might be interested in some sort of trade for the EMaxx
