Beside the Zipper (Chris Heintz) and the PeeWee project (Dennis Harbin), are/were there other ultralights using the Princeton Sailwing principle?
Or, in other words: reading the NASA and the Princeton reports it seems, that the sailwing could be a interesting base for real ultralights.
Who knows more?
