Just curious to know why you are planning on using the Stoots IO-370 and not the IO-390 for your project? Is it weight related or the cost? What does the complete IO-370 FWF conversion cost from Stoots? Are you going to use the Trailblazer propeller or a MT for your 175?
The modification with the IO-390 cost much more than IO-370 and also weight less. Trailblazer 83'' is the prop i wish
