    Went to the local online retailer the other day to buy a couple of 16" props for my 20cc profile plane and saw the 3D props from APC. They weren't in stock so I got the regular electric props.

    Anybody try both and want to tell me and the rest of the world about it?

    I'm listening......

    and thanks in advance :)

    From what I remmeber, the APC 3D props are similar in design to a Falcon "wide" carbon fiber prop. Basically a longer chord for more low end grunt, and less pitch.

    you bought electric props for your 20cc? I don't know if that is a good idea or not, I have always purchased electric or gas prop depending on the engine/motor.
    From my understanding the 3D props are variable pitch, meaning the pitch by the center is different than the pitch at the tip and they average the pitch and put that on the prop. below I have added a paragraph from Xoar about their 3d propellers

    Xoar PJE 3D Prop is designed for optimizing 3D flying performance for R/C Model Airplane. In 3D flying, the aircraft needs to perform aerobatics at various speeds (from low speed to suspension 0 speed). By employing accurate transition of declining pitch parameter from hub to tip, PJE prop provides the aircraft with maximum maneuverability. Xoar PJE’s blades are uniquely shaped to provide absolute balance between thrust and speed and variable pitch for absolute accuracy for the most complicated maneuvers.

    Just to clarify for you Bart is running an electric setup on a 20cc size redwing profile.

    I think I knew that and then forgot... Thanks for the reminder
