Umm the Soloy doesn't do it for me I'm afraid. Apart from ruining the lines.....
I assume it would have an Allison C20 or somesuch.
Would only be of use somewhere you can't get Avgas and you HAD to have a 185.
The engine alone would be three times what the plane is worth really, and as has been pointed out, the performance is largely unusable.
Not to mention the 100l/per hr fuel burn against the 45l/hr of the 0-470.
Be fun not overpitching on take-off and mowing the grass (very expensively) too.
I think I'd rather go for a Porter if I HAD to have a turbine.
