These modes may appear complicated at first but it really does reduce the pilot workload during
both the launch and landing. It is common to spend about a month fine tuning these parameters.

A glider such as the Hornet deserves to be flown with precision and accuracy, as the designer
obviously intended.

The Sanwa SD10-G radio has a full set of menus dedicated to gliders allowing the functions above
to be easily programmed. Many other radios do not have specific glider set ups. In the case of
the Frsky Taranis radio there are many templates on the net that people have built for a wide range
