Weight difference between slotted wing and piper wing?

[glassjet]

Does anyone have any accurate information on weights of the following PA-18-150 Wings?

Piper Aircraft oiginal round tip wing?

Turbine Cub round tip wing?

Dakota slotted leading edge wing?

Dakota round tip wing?

Thanks... Corey

Mark Erikson told me there was 8 pounds between his standard wing and the slotted wing. They have also done some things to lighten the wing also. I think it has lightening holes in the spars. Seems like there were other things but I have slept too many times since I talked to him.

The difference is approximately 8 pounds for the Dakota slotted wing. And that includes the additional material in the slot and to make the wing "square tipped."

The lightening holes in the spar are part of the Super 18 project and are not approved for anything else at the present time.

Dakota's replacement standard PA-18 round tipped wing is obviously less than the slotted wing, but i can't remember off the top of my head what the difference is.
