"The design brief for the Protask was “Simple and Effective”: Three years of development work on the Protask has resulted in a design that has maximized frame-buckling resistance.
Harmonious handling: The perfectly balanced geometry produces excellent drivability, which for most pilots is achieved without extra weights.
Low depreciation: Because of the beauty of the unique design, its stability, ability to convert and high quality workmanship endows it with low obsolescence thus guaranteeing longer ownership."
