ummm, I have had good experiences with their stuff, except when I got in this very wierd crash going throug some water, which I think lead to it getting fried, but im going to send it in, otherwise no problem. I also have their commander, and might send it in for upgrading, i have version 1.

V8(same as V12)
Motor limit none

V12 xc 4-10 cells

All are programable
