APC 16x10E Electric Propeller for RC Airplanes - High Performance 16010E Propeller for Electric Aircraft - Perfect for Aerobatics, Racing & FPV Drone Flying

I only use APC props for my electric models from 8"-3s up to 18"-8s. I've been convinced that 2-blade props are nearly always more efficient than 3 (or 4) blade props, and use them even on warbirds. I'd rather have performance and duration -- after all, once the prop is turning, it doesn't matter. APC's are well made, consistent, come balanced, and are reasonably priced. Occasionally a size I like is only available for normal-rotation (when I'd like a so-called "pusher" for a C/R twin application), but that's about the only complaint I can make.
