Hi Michael, I made the wing leadingedge fuel tanks. I works good. My shift in the weight and balance is not noticible thats great. It is a lot off work to make them, but it is (I think) beter than the fueltank behind the firewall.
For the building of my fueltanks see. http://www.masttotaalconcept.nl/kr2/styled-6/index.html For the intallation we didn`t drill into the spar but worked with a strap around it. http://www.masttotaalconcept.nl/kr2/styled-8/index.html Good Luck with your decission.
