The inventors hoped that E-Volo would be a conventional helicopter replacement device in certain cases such as exploring damaged pipes, taking photos, filming, tracking traffic. .
Thomas Senkel, one of the direct engineers sitting on the E-Volo flight during his first launch, said the invention could be 'revolutionary' in air transport.
3 co-inventors of their E-Volo flight devices, when completed, can be used for various purposes such as air photography, ambulance, reconnaissance and even entertainment only. .
The E-Volo patent group is addressing the problem of how long it can take to fly the device because it is currently using energy from lithium-ion batteries.
Currently, the E-Volo device can only take off for a maximum of about 20 minutes. In the future, manufacturers will hope it can fly for hours by applying more new technologies.
It is expected that the cost of an hour of flying E-Volo will take about 6 euros of electricity. It can land emergency with only 4 out of 16 propeller engines if there is a problem.
E-Volo will be unified with a GPS software and many other aviation technologies to soon complete and serve the needs of users.
