APC 7.8X4 21-25 Free Flight Propeller (APC07840)

It is made of a special composite mixture of 60 %fiber and 40 %nylon. APC propellers, which have a longer and wider design than other propellers, use the power it receives from the engine at maximum even under high pressure and temperature. APC propellers, which have a thinner section than other propellers, thus allow you to make aerodynamic flights with high performance values, even under excessive wind.
