Wow, what an amazing build. I am a big fan of the show and can't wait til the next episode is airing. I just wondered how you did the bearing of the prop axes. In the picture it looks as if you took a sort of a ready-to-use hinge or bearing rather than building it up by yourself. What did you choose? I'm just working on a RC conversion of a Multiplex Fox and i wanted to do the elevation and roll by moving both wings instead of cutting out aileron and elevator. And the wings should be retractable to keep it small during transportation. But at the moment, i am searching for an idea how to rotate the wing without tilting.
