I'm waiting patiently to get my hands on these. I have the TP 40c 3S pack, and this thing is a frikkin monster.

I was debating whether or not to get a 4S 40c pack, but I think that may be a little too much. I've had to replace the gears in my center diff once already...which is one too many times.

a 40c 4S would be just plain murder on the drivetrain. However...a 45c 3S pack? Hmm....that just might be what the doctor ordered.

I must get my hands on some.
