Hello all. Brand new here but I am having some issues with my setup and this seemed like the site to go to. I have several cylinder style batteries, and recently upgraded to a MVP2 rig. When I bought it I was told that my MT3 tanks would work on it. However, I am having problems. The iclear30 tanks that came with it works fine, other than being rather leaky. But when I put my MT3 tanks on, some of them work fine, some don't. I'm at a loss. When I put the same tank that won't work on the MVP on my vision spinner it works fine. Any suggestions? Many thanks for any responses.
