root...On my Mayhem I used the stock fuel tank that came with it. I know many others have had problems with the pressure from the YS. I'm using the YS110 on five different planes. I used the stock tank with each one including the Hanger 9 products. I've never had a problem. I don't wrap the tank or glue it or anything special. I'll continue to use the stock products until I have a problem.
thanks
Barry
