Does cutting all the foam out to fit the tank cause any structural integrity issues with the fuselage? I was studying how the fuselage is assembled last night and it looks like removing all this foam could make the center of the fuselage weak, but then I looked at how the wing attaches and thought that maybe the wing itself strengthens the fuselage because it bolts both forward and aft? I'm also assuming there are more than just a few folks flying this jet with a K30? I'm hoping my turbine conversion kit from HAB arrives this week so I can get started on this build! Thanks for the help, Tom
