APC model aircraft propellers have enjoyed strong acceptance and growth since their introduction in 1989. They are especially popular in pattern and racing events, and are used world wide by top competitors. Multi-rotor aircraft have also taken advantage of the superior performance of APC propellers. The performance and low noise advantages are largely due to the precision methods used to design and manufacture APC propellers.

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, since 1989 and their vast range of glow and electric propellers are widely accepted for offering excellent performance and value. In comparison with APC Slow Flyer propellers, APC Thin Electric propellers are generally designed for higher RPM applications and as such have a stronger hub area and a much more rigid blade structure. Thin electric, slow-fly, and multi-rotor propellers typically blend the low Reynolds number Eppler E63 airfoil (inboard) with a Clark-Y similar airfoil near the tip.

All of our APC Thin Electric propellers come with 5 hub inserts for 1/8", 4mm, 5mm, 6mm, and 5/16" shafts..
