I could not tell if bulletin 25 would apply to KF2 since the initial distance from the root was different from the value listed (96.75 and 97.75). For the KF2, the initial distance is 86.125 inches from the root to the support hole on the strut brace.

So the dihedral is a little more pronounced on the KF2. Also with the KF2, the only adjustment rod is on the right rear wing, so I have less tuning available.
