The Quadraflex AL has a rotational start speed of 4.4 mph.
The Quadraflex AL weighs only 3.5 pounds assembled.
Due to the effect of multiple centers of gravity the Quadraflex was the only planned series of even numbered blade systems I was going to offer.
My hub has been designed with the blade mounting holes
offset from the center line to offset the weight of the bolts.
As you can clearly see in the pictures, by the location of the
mounting holes in the blades, the mass of the blades are also offset
from the center line of the hub. Since my blades are light
and offset along with the hub design I have virtually eliminated
the effect of multiple centers of gravity on the Quadraflex series.
I took the time in designing my 4 blade systems to virtually
eliminate this effect because I know there are several people that
like the look and power of 4 blades.
