Your ALPINA 4001 PRO 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
4001 PRO 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 4001 PRO 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.
Avoid repeated low altitude hand launches on a flat site as this is the most likely
opportunity for damage to occur as there is little time to made adequate corrections when
the model is flying close to the ground.
Ensure that both transmitter and receiver batteries are fully charged and carry out a
thorough range test in accordance with the instructions supplied with your radio control
equipment. Do not fly the model if you are in any doubt about the integrity of the radio
control system – seek further assistance.
Faults do not cure themselves!
Test flights can be carried out in several ways depending on the version of the model you
have chosen; at a slope site from a hand launch, at a flat-field site using a winch, or from
