Actually, if you don't add any ribs, and just stretch the wing by moving all the ribs out proportionally, you can use the holed on the plan, you just get a different curve to the leading edge. If you add ribs or space the ribs differently then all bets are off and you have to recalculate the spar location for each rib. Al > > One other item!!!
