Okay so I tried to add winglets to my Delta 757-200 in FSX using the Ace program. I have yes selected and have it saved. When I go to FSX i see no winglets on my plane. I have tried it with a few other planes and same result. Someone said that you can add it to the .cfg file of the aircraft. where exactly in the cfg would I add that and what should I be adding. can someone do a screen shot? or does anyone know how to fix the problem??
