learning to rebuild a Protank head makes all the diff in the world huh? You have got an air control thingy haven't you? Another game changer for me was the air control adapter.
My Protanks were sitting in a drawer for a long time. When I got my istick however I wanted something lighter for them besides my Kayfuns. I learned how to rebuild the Protank coils and it has brought new life back into them!
OT if anyone has any used Protank heads they don't want please PM me.
THanks!
