Superior performance over the supplied Twin blade. Less noise, but much higher lift and launch capabilities. When asked for advice of their implementation, they knew nothing of my machine. Namely, the DJI Phantom 3 Standard known through out the world. I did manage to find the proper parts and managed to get this machine flying. In conclusion: These Tri-bladed propellers are of excellent quality, made with high precision, and give a lack luster machine, a greater performance experience.

I was using slow fly 10 x 4.7 and was hoping to get smoother flight with the same lift/motor loading. These don't seem to have as much lift as the larger 2 blades. They are really smooth though. Good for video.

Top notch propeller.
Well balanced, light weight and sturd material; as expected from Graupner.
