Build the 4* just how it is, You need to practice you B-tt off before venturing into 100" texan. Don't have one but heard not the easiest to fly. I don't beleive the 4* is a plattform for simulating a texan for practice BUT the 4* is fun to fly and will give you much needed skills. If by chance you want to make it coser to a warbird-Take the dihedral out, clip one or two wing bays and let her rip. No-just fly it. Good luck with the texan-neat plane, love to have one.
