Hi All

Greetings

Aero-Persistence Research has just launched a 4D-aerobatic flyer in the form of a "3D printable" kit in time for Christmas
It was based on their patent pending design:
https://aero-persistence.com/typhoon_4d/

The 3D printable parts are available on the website as downloadable zip file.

Key features:
- Ability to hover nose-down with precise roll control thanks to the presence of wingtip rotors with variable pitch
- Uses cyclic controls for the pitch and yaw and hence it has zero flight control surfaces, i.e. no ailerons or elevators

Here is a video showing the basic hover test:
"3D printable" 4D aerobatic flyer – basic flight test (1 min 58 sec)


Just did a forward flight test today with collective pitch of 11 deg. It was sweet and smooth ~

It uses the Futaba GY750 as it requires 3 independent gains.
Will certainly share flight videos as they become available. All eyes were needed today during maiden forward flight to ensure safety.
