APC Thin Electric Propellers or APC "E" props as they are often referred to, are a range of electric propellers produced in the USA by Landing Products. Landing Products have been producing propellers since around 1989 and their vast range of glow and electric propellers is widely accepted as offering excellent performance and value. APC propellers are high quality, competition proven propellers without the high quality price tag. Perfect for various prop-driven RC aircraft.

The APC Speed propellers are generally designed for high speed applications and as such have a stronger hub area and a much more rigid blade structure. The "E" blades are wider at the widest part of the blade. They taper from that point to both the tip and the hub, with the tip slightly narrow than the standard "E" props and the hub the same as the standard "E" props. They are thicker where the prop transitions from hub to blade and are slightly heavier due to the blade width increase. Specially for use with Speed 400 motors!
