These are a favorite prop choice for the Nano Goblin!

APC propellers are made from composite materials using long glass fibers or long carbon fibers with a Nylon matrix. The performance and low noise advantages are largely due to the precision methods used to design and manufacture APC propellers.

APC model aircraft propellers have enjoyed strong acceptance and growth since their introduction in 1989. They are especially popular with advanced sport pilots and in aerobatic and racing events. APC propellers are used worldwide by top competitors.

Also available in clockwise rotation.
