I have a 1946 J3 cub project.I am new to this aircraft.My question is if I am building or rebuilding a set of wings would you put a extra tank in the wing?I am trying to pay attention to the weight as much as i can.The project came with a just overhauled 0-200 .My youngest son has already claimed ownership when i'"m done with it.I am able to do the work on the plane myself but he will not .Is it worth hauling around the extra weight ? I would hate for him to need it and not have it.
