I agree. I don't think you are going to gain enough benefit to justify the added weight you are going to get. The best mods for a 4-Star, in my opinion, are cutting a couple bays off the ends of the wingtips and take out some of the dihedral out of the wing. Doing those mods will really wake this bird up and make it fun to fly, but still keep it tame enough for newer pilots<div>
