Yes Ive tried it - it works OK but can be improved by reshaping the lungs.
Just turned the originals around and put them inside an AP wing to keep em together.
As I bought the MK15.5 I didnt continue.
AP is still 'testing' Dave Thompsons ones and they may be available at some stage from the factory - but dont hold your breath.
See if I can find some pics - got some of Daves rear lungs somewhere.
