After I reviewed a couple of sites and some research on some license sites I decided for myself to make use of the Creative Common License. I think at the moment this is the most suitable license I can go for. Maybe I will change this to a later but for now this will be it. Below there are a description about the license and two links that may help to chosse the most suitable licensefor any needs.

The licence above applies just for the hardware, here the spaceframe and the joints used in this project and also the flight-controller based on the satshakit.
The software MultiWii, used within the project is under GPLv3 licence. The GNU General Public License is a free, copyleft license for software and other kinds of works. This also covers any modifications I did, based on this software.
At the time beeing all models are in a kind of beta status, also the next model will still be in development because there are still a couple of issues that have to be solved.
When I have the first real successful flights with the redesigned spaceframe I will public some videos and documentations on my site and also on Youtube and Vimeo. Also I would like to participate on some events with it, especially with full functional He-Vessel because this is sure one visual statement that makes the difference besides the space frame.
As for noncommercial and educational purposes everything will be for download ready as soon as I have a fully functional system. I like the idea of sharing knowledge and ideas freely. And if anything is on a opensource or similar licence build up then I understand and support also that any offspring of it is published and licenced under the same conditions. But I also support and understand if there is a limitation for commercial use for what ever reasons. For myself I am willing to publish anything that I develop or invent in future under a licence as the Creative Common NonCommercial licence, that for the moment i found the most suitable for my projects.
My plan actually is to redesign the spaceframe to eliminate the issues that came up during the build up process also to reduce the numbers of parts. Simultaneously optimizing the stability of the joints without increasing the weight of the parts. What I want to achieve for the next run, is to achieve a protoype close to a ready for production state. At the end developing addons and optimizing the software part stands on the list. Any commercial usage at the moment is pure fiction and to be true as long as my project doesn't reach a certain stage any commercial thoughts are wasted. This doesn't mean that this won't happen in the future, but to serve any commercial request of a numbers of the hybridcopter I should look out to optimise the complete workflow from producing, to manufacturing the parts and the build up process. This, as I mentioned before, will be also reconsidered during the redesign of the project.
