Proper prop selection is a very difficult and expensive task.

Rick Neilsen

I would like to buy the blades 3 or the whole prop (Warp Dive only) - since it is easier to cut & grind & we have the facilities to do it.
Need three 68 inch up to a 72 inch radis Warp Blades. Some damage OK since we are going to cut & grind them anyway.
Any of you guys got one you would like to sale - cheap. The Prop noise is what we are really interested in.
Already looked at BarnStormers. May not amount to anything.but you never know.

"But the finding has lots of applications on land, too. Putting bumps across the leading edge of a wind turbine means the blades can be oriented at a higher angle to capture more of the wind without worrying about stall -- which can damage the turbines.
They are also targeting industrial fans. "We can move more air and ventilate more area with fewer blades.
The whale-inspired fans also use 20 percent less power and operate with one-fifth the noise of a standard fan, Dewar said."

That''s good, but VGs have got my stall speed down to 25 mph. I would
like to fly backwards,
but have only seen that done by my friend Greg Elliot (THE Possum) do
that with a head wind on
Jekyll Island (smooth off the water). No wind on the ground - so he
wanted to lower a beer down to
us. Had the beer, but didn't have the string (fishing line). I have
got down to about 5 or 6 mph Ground
speed GPS. Impressive for the guys on the ground.
