I cannot find plans for an old design that I flew in the 70-80’s so I am going to try to duplicate it. This plane used an Ugly Stick wing mounted as a low wing on a rolled plywood fuselage. I am going to scale this up a tad for my YS91 and I am thinking of going with spilt wings mid mounted with wing tubes. My question is this. The Ugly Stick wing had unique wing tips if you remember them. I see a lot of 3-D fun fly planes these days with no wing tip what so ever. Basically just a last rib. What is the advantages and disadvantages of just going with no tip design or should I still use the classic Ugly Stick wing tips?

Thanks
