The throws are measured at the point of maximum deflection – in millimetres:
Normal Flight
Rudder
Elevator
Ailerons
Flaps
We recommend about 20% exponential in the elevator channel. The flaps may be set
to move upwards, half the travel of the ailerons for full control of the trailing edge
Thermal Setting

The flaps should not move with the ailerons, but some model pilots prefer to mix the
flaps with elevator (Snap-Flap) in this mode.

In this mode the flaps may be set to move both up and down, about half the travel of
the ailerons.

Your ALPINA 2501 ELEKTRO is now ready for the first test flight.

First Flights.

Experienced model flyers will now be waiting for the first opportunity to test fly the
ALPINA 2501 ELEKTRO and fine-tune the setup to best suit their individual style of
flying. The following advice is intended to help those with less experience to carry out
the test flight and successfully trim the model:
Every flying machine, from the most humble chuck glider to the full size aircraft, must
be test flown and trimmed after completion and your ALPINA 2501 ELEKTRO is no
exception. The slightest deviation in manufacture or construction can lead to minor
variations in flying characteristics and control responses. Test flying is the means to
optimise the centre of gravity and generally fine-tuning the control response.
