Exciting news -- we are shipping the new "battery" version of our large capacity MH900e endurance racing tank.
The (pdf file) attached to this document is a supplement to accompany the existing instructions for installing the original version of the tank. The only additional parts required are a longer starter cable, M6 screw, and a spacer. There are no permanent alterations required for this REV-B "battery" tank to be installed and work. More info, too, on this older news article.
Both versions of the MH900e Endurance tank are $899. We support the tanks with a "no questions asked" lifetime replacement policy. Even if you accidentally cross thread one of the screws and mess up the tank upon install, we take care of you.
