I only have the all glass prop to measure against which weighs a whopping 195 grams. A beautiful piece of equipment tho and is worth copying or modifying to suit. So the part carbon prop weighs about 150?
I'll try to remember to take my camera for photos. Weather looks fly able so I'll head to the field soon.
The 21 X 10 Carbon weighs 125.5 grams. 39.5 grams lighter than the 21 X 10 Nylon/Glass.
It spools up quicker and verticals are much better.
