To be sure that itīs mentioned: At all time, stick to the limits of the machine!
Some "basic" manoeuvers would look impressive to the pedestrians (in no particular order):
- Hover and hovering turns in both directions
- Slowly changing from backward hover into forward hover and vice versa
- Hover circeling around some visible fixed object (wind indicator, ...) with the nose (or tail, ...) always pointing to this object
- Hight speed taxi along the runway with a quick stop into hover
- Vertical takeoff
Everything of course depends on limits (laws, aircraft, weather, air field), skills and practice.
Start with the most simple stuff
