Just remembered something else, If you have a problem with reverse not being fast enough, you could check the first file listed in the following link. http://www.lawnsite.com/showpost.php...&postcount=108
It won't make the two wheels go the same speed but it can speed up the reverse if that is a problem.
Thanks again, LCPullman, I will look at the link...speed, however, is not important. I don't have speed, but would trade it for 'eveness' if I could. I need the reverse to get out of situations on a hill, even power is what would work best for me, speed would likely spin the wheels. maybe I'm egtting caught up in words here (speed, power, etc) but I think you know what I mean to say. Thank you.
