Does anyone make an aiflow control valve that fits ego thread? Or is ego thread on the tank side and 510 on the battery side (aiflow adapter)? Not looking for a base for a specific tank, but something that goes between the battery and the tank base. I started with Protank 3 mini and Evod 2 mini tanks. I have been using other tanks with better aiflow, but I still like the Evod 2s and don't want to stop using them. An aiflow valve would go a long way with them I think, as the one for my protank 3 mini made it much better. But that was a replacement base that was made for the protanks and aerotanks and will not fit the evod 2 afaik. I would really like one that can be used on any ego tank. I guess if there is something specific for the evod that would work.
