Standard Propellers are build for clockwise rotation. Counter rotating propellers are used for push drives with non electric motors or for Quad/Hex/Okto Copters that need left and right rotating motors to allow stable flight control.

Hello. are also used depending on the location of the engine, and you can be reached to pull or push (Maoescobar)

Normally in planes, we use standard rotation. However, in some models (such as quads) you will need two standard and two counter rotation. If you use a counter rotation in a plane they will be pushed back!

They are useful if you want to push or pull without changing the rotation of the engine. The shape of a propeller blade, infact, is similiar to the shape of a wing, so it has a edge of attack and an exit edge. So, if you change the rotation without changing the shape the propeller will be no more efficient.

i m not a quad guy but counter r rotating props are good for the twin engine planes so the vibration of the engine and props doesnt make the plane roll .i will use these props with d 2826 2200kv for a twin engine plane after some tests

This is a set of standard and counter rotating propellers. You need only one type set...or, better, a pusher propeller. What motor do you use? I guess a high KV one... maybe a 6x4 or even 5x4 could be of use for you.

This propellers has hole for 3mm shaft and I am sure, that will be fit to a proper saver. But you can also drill bigger hole into propeller if you need.

Yes! Really a very good buy. They are ideal for use in quadricopters.
