I have had both the first and second edition of this plane. Both are good flyers. The 91FS will work very well. Here are the changes that I made that improved the flying. Reduce the dihedral when you build the wing by about half and also move the aileron servos out into the wing instead of using a single one in the center. I made this change after experiencing aileron flutter on mine and have seen others with the same problem. The other issue with the first edition is the covering is the sticky back shelf paper kind not the good heat shrink type of the second edition. You can patch with ultracote if you keep the iron temperature low. The second edition had these mods already done in the kit.
