Our blades sets are sold and carefully
weighed and balanced sets. We do not sell single blades since
they could cause your existing blade set to shake and wobble.
If you break a blade you will need to buy a new set. This is
for your protection since a rotor grossly out of balance could
break PMA's bearings.
17mm ID hubs that fit most late model
Delco PMA's - Made from top quality steel.
New round shape allows single hubs
to be practically indestructible in high winds!

This hub is used for
making either 6, 3 or 2 blade systems. "Hub-Bub Talk"
THE "MORE BLADES" THEORY and
ARGUMENTS-
Wind turbines experience "PROGRESSIVE
LOSS" or Cascade Failure when under heavy loads.
This means that the slower the rotor spins under load the MORE
likely it is to spin even slower and so on (Cascade Failure)
until the blades are moving so slow they can't catch enough wind
to be effective any longer because of excessive "Way-Holes".
This is why two and three blade systems need a computer to keep
the blades rev'd up to speed. The computer removes the load by
making fast adjustments and this keeps the blades moving quickly
eliminating cascade failure. However a computer become less necessary
when you have lots of blades working for you since cascade failure
is greatly reduced by having the extra surface area of 6 blades.
3 blades will work just as good as 6 blades IF the design is
100% perfect. Having 6 blades is an EXTREMELY forgiving system
for those of you experimenting with using motors as generators!
"Cascade Failure";
The slower a blade spins the more
likely it is to spin even slower and so on until it can no longer
adequately catch wind as "Way-Holes" form in the propellers
diameter matrix area.
"Way-Holes";
A potential power producing area
of a wind turbine propellers diameter that is allowing air to
pass through in-between blade strikes.
or - The absence of a wind turbine blade in the winds path at
any given point in rotation time usually caused by over-amperage
loads including connection to lower voltage batteries used in
low wind speed areas or high amperage appliances or lack of blade
area in the original turbine design or a mismatched PMA to blade
area ratio in the design.
IT ALL BOILS DOWN TO THIS ONE SIMPLE LITTLE QUESTION IN THE
END.
The REAL question becomes, WHAT is cheaper. Extra BLADES
or COMPUTER controls???
Well, at least in the case of small wind turbines it's a
no-brainer,, Extra blades are much cheaper than electronic controls
and definitely more dependable too!!
In the final analysis more blades equals super low wind speed
start up plus the added benefit's of simplicity and dependability.

Warning:Please
note that these blades are very sharp and can cause severe injury
if handled improperly. Treat these blades with the same respect
you would have for a sharp sword.These blade
sets can turn at well over 2000 RPM on a windy day and can cause
severe bodily injury when they are spinning. Use extreme caution!
Never mount or work on a wind turbine on a windy day. Never place
a turbine in any area that can be accessed by inexperienced persons
or children. We assume no liability for ANY injuries caused by
these products.
Love these blades you were right, wow can they
turn on, im getting up to 40
volts out of my indiana general dv pm motor,there scarey sometimes,
im
putting it on youtube for all to see, thanks again

Dear Bob: I thought I would drop
you a line and let you know about the turbine I ordered from
you, it was to replace a southwest wind power windseeker 503,
because it continually trashed the blades, I have gone through
three of their sets of blades, and now they stopped making and
servicing them. As I was assembling the one I received from you
the windseeker was on the bench right next to it, and just for
the heck of it I thought your hub and blades might go on the
windseeker, which it did, I remounted the wind seeker with your
hub and six blades and never saw it do such a good job, for nine
years I have been hiding from this thing, and now I can stand
right underneath it, your advertisement on your web site is 100%
truthful, your blades turn with very little wind, and they withstand
very high winds, and make very little noise, and virtually no
vibration. I would recommend your blades to anybody that wishes
to improve their current Wind Chargers. I haven't had a chance
to mount your wind turbine yet as I am waiting on another set
of blades. And if anybody wants to know about your customer service,
I would highly recommend them to you, you always answer your
e-mails and are very helpful.
thank you

to spin CCW just build a DOWN-WIND turbine design. EASY !
