The sc10rs has decent electronics, but it depends on what your nephew wants to do with the truck. If it's for bashing, perfectly fine w/stock electronics. If he wants to start racing, then he'll want to replace the servo. It only has about 40oz/inch of torque & 0.24sec/60degr turn. So, not ideal for racing. Receiver/controller is okay, but doesn't have any of the more advanced controls, such as adjusting throttle exponential. The rest of the electronics are okay for racing, and definitely fine for bashing. Motor is actually decent. It's 3300kv, so about 13.5t sensorless. It's got a decent amount of torque. ESC is okay also.

Hope this helps,
