Great info as always,thanks guys. I am considering building aluminum
fuel tanks. I know some have failed in the past but I dont like the fiberglass ones that came with my kit (Kream coated).
Another question did any IVs come with a header tank only? If so what did the factory do to the wings to reinforce them? Drag, Anti drag bracing?

Has anyone used the plastic replacement tanks? Looked like you would loose
most of the original structure the fiberglass tanks provided?

If I build new tanks,I might incorporate a horizontal baffle "X" to provide some extra strength ?? Building metal tanks as light as glass tanks will be a challenge even W/O extra bracing inside. Need to keep the weight down.!!
