The key to his question is the desire for a non-RTR RC. The Savage is a great truck to get as a kit, but as mentioned the T-Maxx can be bought as an RTR. Then you could dump the stock radio and servos. I have one of each truck. In both cases, I dumped the stock radio, receiver, and servos for my preferred radio, receiver and servos.
It is entirely up to how much you want to spend and what you are looking for in a truck. Do not let the RTR be the only deciding factor.
