Soloy & PT6 conversions are all upwards of $500K which is exactly what this thread is all about , which is trying to find a cheap turbine jump plane solution.
The Walter Turbine with mounts & accessories are about $120K , the engine alone new is only $50K so ... if you could get an old 207 and have this fitted you would have a great jump machine for under $500K
This would fill a huge gap in the market for the skydiving industry.
