Performance 0945 Black Multi-Rotor Drone Propellers - MR Series - 9x4.5 Prop Set x2

This prop set works great for me on my plane. I only have a single motor so I would prefer having two props that are CW but they still work great. If I do want to use both props it's fairly easy to change the prop rotation in my radio. The props are very well balanced our of the box so I didn't need to do anything prior to installing them onto the plane. Great quality. I am very happy with them.

These are matched pairs of opposite pitch, or counter-rotating props. Unusual to find and I am using them in twin-pusher electric RC model airplanes. The counter-rotation cancels prop-torque and consequently leads to zero-roll under throttle. The props are well-made and balanced.

Survive two major crashes with only marks on the finish. Extremely efficient design increases flight time by several minutes with great performance.

Don't expect to install these when you get them because you will have to purchase additional parts

Using them on an opposed rotation twin RC aircraft. As soon as I got them on and hit the throttle I could tell they were pulling more than the standard size 10x4.5 props I had on before.
