The

Project

The time has come to completely rethink Aerobatics. A dedicated team partnered together to develop the first electric aerobatic aircraft capable of flying an advanced FAI aerobatic program. 
 
The team, consisting of main sponsor Hamilton International, Siemens, Renata Batteries, Silence Aircraft, Hangar 55, Insysta, Tonic and Cimark developed and built this new, eco-friendly aircraft together. 
 
The best components were selected, starting with the Silence Aircraft Twister, one of the most efficient aircrafts flying today, Siemens electric engine, a highly performant electric engine, knowledge and technology from Hamilton International – a Swatch Group company; and project management skills of Hangar 55 to assemble this innovative aircraft in record time.  
 
In addition, significant support was provided by Insysta information systems which houses the huge database, Tonic which helped with media presence and Cimark, which opened many technology doors.

The

Plane

The Hamilton aEro Twister is a very light and efficient aircraft certified to fly aerobatics between +6 and -4 G. The fiberglass airframe is stiffened and strengthened by carbon elements, while the engine provides up to 100 KW power and a 45 minute-flight autonomy, including 15 minutes of aerobatics. The weight/power ratio is 4.2kg per KW, a ratio quite similar to an Extra 200, providing the required performance needed for aerobatic training.

Safety is a main topic topic as the plane can be used for demonstrations but also for beginners to train and therefore needs to be easy to operate. The Siemens engine proved its ability already in the air and is very reliable. Each battery cell has its own processor to control and monitor the situation: in case of overheating, up to 10% of cells can be switched off independently, allowing the pilot to fly back to the airport safely.
 
Another key aspect is sustainability and ecology. The plane defines a new way of flying by being CO2 neutral and emitting a very low noise profile. Together with other developments, this project supports the future of aviation through environmental-friendly initiatives and a long term vision. Finally, cost is also lower – about 2/5th of a regular aerobatic plane – and is aimed at attracting not only experienced aerobatic pilots but also young people who cannot currently afford to start the immense adventure of flying a plane upside down.
