*At normal wingloading with standard trimmers, Vmax = 57kmh. Measured with GPS for true horizontal speed, not airspeed as horizontal speed + sink. At above average wingloading, or with an airspeed indicator, Vmax 67kmh can be achieved (check other manufacturers speed claims for this common discrepancy). OZONE believes that the true ‘normal wingloading’ speed of a ppg should be accurately measured and published - for the Viper 2 this is 57kmh. Our testing has shown that the Viper2, at 57kmh, is at the top of the class in terms of speed and glide when loaded normally (i.e. one solo pilot with foot launched motor).

* Weights may vary up to 50gm per size due to slight variations in the manufacturing of the fabric used.
