RE: Sig 1/5 scale J-3 Cub wing assembly
If you have two pieces ,( one for each wing) put them end to end to see if there is in fact any difference in the shape depending on orentaion.....you could figure out which way is up that way..or draw the end pattern on a piece of paper and turn it over ...It is hard to tell from the pics but it dosent look like it would matter which way it went .
