Well its not in any of my books, and if its not on the net I guess I may have to call it a day.
Slightly academic therefore, but just in case I've missed something:
- it is based on (but not converted from) a Piper Cub variant. So in otherwords it was, at the time, a new build aircraft (hence I can't find any reference to it under Piper)
- it is American
- it was used for research purposes
- you can't find any reference to it on the net (so no point in searching Aerofiles.com!)
As for research....I'm just trying to think what it could research...stall speeds??!!
And "based on" a Cub variant....would that variant be the PA-18?
Care to give another clue....year/decade of manufacture maybe?
