Whats up bud. To be honest any RTR will need upgrades. Doesn't matter the manufacturer. RTR's are just mass produced cars/trucks with the cheapest parts and electronics available. To get them out and on the shelves.
They all are designed with breaking points. So the harder you bash the faster you will need to replace parts.
Depending on what your looking for. And how much bashing you plan on doing. You could build a bada*s basher. For about the same or little more then a RTR.
Since you will need to upgrade most electronics. Including the ESC and servos. Along with the A arms, hubs, shocks and Pinon/spur gears on a RTR.
@DavidB1126 listed a well rounded line up of RC's. That are all good bashers. But will all need upgrades. Depending on how hard you plan on driving it...
