The next-generation SV concept made of G1 duralumin achieves a high level of exhilarating cast feel and trouble-free performance, and increases flight distance. The stroke of the induct rotor, which previously operated in one stage, has been extended to achieve a second stage stroke. At low rotations, only the first stage stroke applies a moderate amount of braking, and at full cast, after the optimal braking that takes full advantage of the second stage, it returns one stage to maintain a weak braking force in the second half of the trajectory, resulting in the second half of the cast. , contributing to increased flight distance.
