THe PT6 was originally designed as an oil pipeline pump in Canada.
The Garrett, an american war throw away helicopter engine.
I'd rather have the one built to fly than the one built to stay on the ground
From my perspective the Garrett was a better engine. A little trickier to start, but if you kicked it in the guts with a series start once you had light off (starting the first engine) it was always a faster, cooler start. A battery assisted start on the second engine was preferable to a cross generator start to save current limiters.
The nicad batteries will also add to starting woes if they have not been upgraded to the lead acid spec.
Nothing worse than on a 40 plus hot and high day watching a poor soul starting a hot Garrett.
it could sometimes take a while!
I certainly miss the metro salute on every ramp you arrive on
