I can agree that the plastic chassis is actually a good design and I do live my Revo I just wish I didn't have to out so much into it to make it last. Summit drive shafts are a must have they are a wonderful design and last forever. The diffs even when shimmed properly are pretty weak. So I swapped in lst diffs. The slipper assembly is pretty good if you put an old tmaxx brake disc in place of the slipper pads. The rod ends on the push rods and turn buckles develope slop very quickly so those have to be replaced often. Don't ever wasteoney on the traxxas Cvds they are junk and bend very easily especially if you run rpm arms. It's a good design it could use some refinement and better quality parts to be on par with the rest of the mts on the market. I still have mine and still drive it. I just wish it had been a little more durable right out of the box.
