what happens if the out side flap is 2 in shorter than the inner flap

  I'll say that what happens depends on the chord of the flap, and how much it deflects. The inboard wing tip is flying a shorter distance and slower than the outboard, and if the outboard flap is shorter near the fuselage, it can have an some influence.
   Next question is, how did they get that way??

Sounds like something that might have happened in the earliest days of stunt where the thinking was that the inboard wing needed to carry the weight of the lines so had to generate a tremendous amount more lift than outboard-ala the All American.   You sure would have zero tip weight.  It would be a task to trim this thing to anything like modern standards.  If it were a modern mess-up,   fix it.  I actually have a slightly larger outboard flap at least in chord width (3/32").

i am not aloud to be in the same room with any measuring instruments

   So what you are saying is, you cut it off twice and it's still too short?? Measured once and cut thrice?? That ok, we still love you RAD!!
