I finally got the hacker 8L c40 hooked up on my rustler. I used the heavy beadlocks just too see what it could do. Went crazy with the gearing as well, and used 87/26 with 5s1p A123 cells. I never was able to blow the dirthawgs of the beadlocks before. I finally did it Wheelies were on demand with the heavy beadlocks on. Just nuts.
