I would like to share this document so that we can all solve our problems regarding the keel by the Czech gentleman that I bought on Kickstarter after several attempts to revive the battery in the end I broke the propeller that came with the device when I broke it, I have discovered the screws that fix it to the engine from there I was able to make a 3D copy to be able to attach the screws and I had already heard about this type of new elite for a long time and thanks to you here after modifying it I think that about 30 times less bad than I only printed it seven times. I think that with this one we can attach another propeller to our purpose. In any case, I would like to thank everyone for the collaborative project that is this protocol. I adore you and I love finding information from so many people that surpass my intelligence.
Well, the propeller so that it has a good screwing system, I made some holes from above, drilling the elites. I hope you like it since this is my second remastered project that I share.

Thank you very much to everyone
