If I had started out with a ProVari and ProTank2s, I would have quit n frustration. The PT2s only worked well once I replaced the poorly thought out bottom caps with Tatroe caps. I had my Halo Tritons to use in the meantime while sorting out the issues with the PT2s...
don't move the goal posts.
protanks are garbage IMHO. advanced user level work with beginner level performance at their very best... and you have to know how to get that out of them and keep it that way.
