I added the Losi optional aluminum steering plate and servo saver arm as I heard this could be a weak spot. The wide Robinson (48T) gives me gearing closer to the stock truggy and because it is wider the wear on the pinion/spur is reduced. I am using a Losi Smart Diff in the center, I have one in my buggy and it works great. I did a quick paint job using Parma Faskolor paint and I covered the nitro motor hole with a lexan plug.
