TRIMMING AND FLYING YOUR MODEL
When flying your model, choose a large area
free from any obstructions. Do not fly it towards
people or property.
To fly successfully, your model must be correctly
trimmed. Trimming is a normal procedure for any
aircraft, but for a free flight model it is especially
significant as once the model is released, you have
no control over it. Trimming takes some time and
skill and the basics are outlined here. More detailed
information and help are available from the many
experienced free flight modellers who have websites
dedicated to the subject or post information on
numerous on-line forums.
The first step involves fitting the motor and
checking the balance. Short flight tests should then
be carried out during which the behaviour of the
model can be observed. Following initial flight tests,
the number of winds on the motor and thus the
duration of the flights can be slowly increased.
