When SWMBO insisted that the fans would be fine outdoors even though they

I will get two sets at ReStore at $3 per set, and see how long they last,

Thanks for the info, guys.

When you buy the blades, will you also be buying the mounting
brackets?

Even if the mounting brackets line up with the holes in your motor,
the angle may be an issue.

Cheaper fans use low blade angles so they can use a cheaper motor.
Increasing the blade anlge might cost you more a lot more than $3 a
set.

*At the speed those things turn, the blades could be vertical and not
harm most of the ceiling fan motors out there.- Hide quoted text -

Here's the llink to one of the many, many sites that stress the
relationship between blade size/angle and the power of the motor:

http://www.lampdepot.com/ProductCartPages/page111.htm

I quote...

The most powerful, durable and expensive motor is a "Stack" or "K55"
style motor. ... The power allows for 14 - 16 degree blade pitch and
use of wider blades so you get more air movement.
....
Low Grade promotional fans use small motors to move narrow blades at
near 10 degree pitches. The result is much lower air movement. Often
having lifetime warranties.

Fan ratings : Performance, Medium, Moderate, Promotional

Performance 14 -16 blade degree --- Stack or 188x20 motors
Medium 12 - 14 blade degree --- 188x12+ , or 172x14+ motors
Moderate 10 - 12 blade degree --- 153x15 motors
Promotional 8 -12 blade degree --- 153x13 or less
