Received my new prop yesterday. It's an NR SR 106 2 blade scimitar style with a metal leading edge.
Looks nice. Low weight is impressive, 9.9 lbs. all up weight including bolts, backing plate and spinner.
Not including the 2" prop extension. The pitch tool is set at 16 deg. and can be adjusted plus or minus
7 deg.

It will be awhile before I can do any testing

Air Trikes re-brands the Luga under "Kool", and some refer to the luga as an "NR prop", presumably
the initials of the inventor (Nick Roman)
So:
LUGA = KOOL = NR Prop.
