I like the XRS ESC you got. Since that thing came out I've always thought it would make a great ESC for the Hybrid. But isn't it only rated to a 15-turn motor? And you got a 14x2? Ah, I see, you just had to push it to the absolute limits of its operability. I guess that's typical of most people.
How are you running 4WD with those batteries across the whole chassis? Do you have the belt installed? Well at least your runtimes should be decent, but your setup will be much cleaner once you get the 4/5SC cells. Anyway, looks good! Keep it up.
