A friend of mine just got into the hobby, and that's exactly what he got. So far, we replaced the steering servo, and added a rechargeble reciever battery. It still needs a new radio, the reciever that came with it doesn't seem to give the steering servo full power. It's alot better than the one that came with it though...the stock seering servo could barely turn the stinkin wheels! We upgraded to a JR 650, wich is great, but a 590 would do just fine. Anything with 100+ in oz of torque...
The only problem he's had so far, is the center shaft link to the rear diff slung the set screw. You just need to go through it, like any RTR, and tighten things down, and add lock tite to anything that spins.
