Agree.
In fact if i was to keep 1 RC-car it would, without a doubt, be the Summit, it's just the most versatile and fun truck! You can literally drive it anywhere.
BL is a must though to satisfy the need for speed. I've waited a year or so to upgrade motor & ESC but now I'm wondering why, it's so much more alive and instant fun than before.
In converting it to BL I've given up all weather capabilities but I don't care, there's no comparison with stock motor & ESC.
But Traxxas should really do a BL waterproof one though!
4S is enough imo, at least it stays alive a bit longer.
