The Alpina 2501 with its incredibly stiff wings, fitted with ailerons and curvature flaps, is geared towards high performance and is aimed more at experienced and demanding pilots than at beginners.
In our test flights, the profile of 11% thick, internal development within the company Tangent was shown to be particularly convincing.
Even in extreme wind conditions, trajectory stability and aerobatic behavior remained exemplary. The wings provided with judiciously arranged reinforcements, show no weakness, even in my most violent maneuvers.
The fuselage with very pure lines, allows the installation of propulsion from 250 to 500 Watt and Lipo batteries of 3S 11.1v from 2200 to 2500mAh.
Even in very low flight conditions, it is possible to obtain climb rates of 10 to 15 m / s (depending on equipment), thus making very pleasant flights possible.
The Butterfly combination (ailerons + flaps raised) allows very easy landings, even in difficult flight conditions.
