ESC issues???

[mckrackin]

My rock crawler seems to have issues with the speed controller.
Forward is always OK but when I go to reverse,sometimes it goes and sometimes it doesn't.

Also,since I upgraded to 4 wheel steering,even forward movement is iffy if I try taking off with both sets of wheels turned.
Maybe the second servo is taking too much power?

Are there some good brushed ESC's with high power tolerence and precise movement control?
Maybe I should just go with a high end brushless set up?

i don't know how to help you but on my new ESC with forward/reverse/brake i have to let go of brake before i can reverse. it takes getting used to for me.
