Surely nice piece to play with..
I only just read that GE bought most of Walter Aircraft Engines in 2008 or so.
Piper want competitor for SkyCatcher, 'ready to roll' out, GE want M601 tweaked and compete P&WC's PT6 engines.
The article in one older LOOP was interesting. I still find Shark Aero even nicer design, obviously, with 'sharky' features. What more, tandem seating in Shark brings some nostalgia.
