Prop confusion

[Jackson]

Basically I'm confused as to why some props don't list CW or CCW.

As an example.

http://www.buddyrc.com/gemfan-thin-electric-8x4-inch-propellers-a-pair.html

http://www.buddyrc.com/gemfan-direct-drive-8x4-inch-propeller.html

vs.

http://www.buddyrc.com/black-gemfan-8x4-5-inch-slow-flyer-reverse-propellers.html

http://www.buddyrc.com/black-gemfan-8x4-5-inch-slow-flyer-normal-propellers-x2.html

So if they are listed as Direct drive or show no CW/CCW they are only for planes?

And how about shape?

Note: This product contains 2 normal rotation propellers

These are called "normal rotation propellers", has to do with planes.

I looked through the links and they all seemed to saw what hand they were, just said it different ways.

Hi some are pairs so its 1x CW and 1x CCW, the second link are duel so can be mount either way to get the cw or ccw
All the blades in the links are aero or multi rotor most are sets one of each, or two of one rotation

the second link are duel so can be mount either way to get the cw or ccw

So just flip them over to change rotaion?

Yes, some props are reversible, just flip them to change rotation.
