Hi guys... I'm new in this area of rc..just purchase ft sc 10 4x4, i have been reading this thread as well as rcshortcourse thread.....its seem that diff on the original sc10 have problem which did not get enough brake so you can't handle the car on the air...

is it true? or do i have to buy cdiff from rc shock? or exotek one...or the option part from ae will be enough?

And also i'll be using hw sct pro with 4000kv 2 pole..what will be the start gearing on big outdoor track...

thanks guys
