RE: 25 or 4.6?
I would have to agree. My first rc was an RTR amd whenever anything went wrong I wouldn't have a clue how to fix it. When I bought my Savage I made sure it was the kit form. That way you know the truck better from the start and also have a full and very detailed set of instructions on how to put it all together again when the inevitable happens. Get the kit, you wont regret it.
