Do rotor blades come in different spin "directions"

Default Do rotor blades come in different spin "directions"

I am brainstorming on a project and wold like to use a pair of rotor blades as mini airfoils. Are there any blades made in both clockwise and counter-clockwise rotation orientations? Maybe a counter-rotating system? Or a heli blade that has a symmetrical airfoil?

A stock BCPP comes with symmetrical blades that allow you to do inverted flight (which means the motor spins both CW and CCW). You can pick up a set of symmetrical blades for 23$ CDN... that's something like 20$ US.

Have fun, and good luck,

that is not quite true... maybe it looks like they are spinning CW and CCW but as far as the heli is concerned they haven't changed.

You could spin those blades either direction and still product lift because they are symetrical but you are not changing their direction of spin simply by inverting the heli.

Um... I dont follow that one... I havent ever seen a heli spin the motor or mains backwards for inverted flight...

Kinda hard to instantly change direction when the mains are spinning at 200mph isnt it?

That post came out late at night - so I must have screwed up.
