First link is a scratch built version with bolt on wing panels. Second is an Outerzone plan showing a bolt on wing. Should be helpful on how to do it. This plan shows a removable top hatch. On another version it shows a removable bottom hatch.

I couldn’t post the plan as not allowed by OZ.
Search Outerzone for Hots plans
Seems like the removable top hatch is more popular.
