Is there a website for NSI? The phone seems sooo primitive. :-|

I'm on the lookout, too, for a lightweight electric adjustable prop
for the 180HP range. AirMaster regretfully suspended work on their
model, which looked GREAT at Sun'n'Fun a few years back. The MT is a
little too heavy and too expensive, I think. AeroTek has a
four-bladed one that looks OK, but very few in service. I won't go
near an Ivo Magnum.
