so how does the fuel tank thing go again? what is the centerline? up and down? or left and right

and what of you move the tank so you have teh muffler at the bottom( that is how i would like mine)

but i don't plan on using the In-Cowl pitts style muffler

so i guess i have to cut the cowl away so it clears, but at my hobby shop they have a bin full of stuff for half price., they have on in there for regular price at 37.99 so whatever half of that is i can get one for

thanks,
Scotty
