I recently read about a guy in Arizona looking for other Arizonans. But I lost the mail on it. So I think your idea is great. I am Peter Sanchez From: Mesa Arizona Building: Kr2s Powered by: Corvair stock 110 Status: I currently have entire fuselage completes plus spars. BUT, Big BUT. I followed original plans and want my better half to fit with me. Because of this, I am starting all over. Going to widen 4 inches at least and have been saving my AS5046 wing templates for this conversion. I have the RR prefab Turtle deck Canopy and frwrd fuse which I intend to use by splitting and widening. Basically, dumping 3 years of stolen hours to widen and add all the new goodies to make a better plane than what I've got currently to include the outer wing tanks.
PS. Anyone reading plane and pilot, there's an old article concerning outer fuel tanks on the piper 235 which I enjoy flying. Goes into good detail about the advantages of the weight of fuel being carried by the outer portion of the wing. Outer wing lift factors sustain its own weight. This as been discussed in other mails read. This does alleviate pressures on the center sections.
