Product Description - 3D flight with intense power and torque that changes instantly.
The O. S. SPEED 91 HZ-R3D was created in order to respond to such an ultimate request from a pilot and generate the power that he wants throughout the flight.
The engine head of the exclusive design is given a combustion chamber shape that is compatible with 30% nitrofuel, which is common in 3D flight, and of course it is a cutting head that boasts high heat radiation.
It is combined with the body of the same color to produce a whole body with black anodized finish for a cool appearance.
The carburetor diameter has been expanded to an appropriate size to match the power of 3D flight, and the exhaust port shape of the cylinder has been changed to an optimized design considering the output characteristics.
In addition, the DRS equipment that boasts a stable fuel supply that is not affected by violent attitude changes remains unchanged. The crankshaft with high rotational frequency has been redesigned to improve stability during overflight by reviewing the balancer shape.
