VTOL aircraft

I'm presenting my project, a VTOL personal riding aircraft.
I finally got the textures and animation I want, but the file now is so big. Somewhere I read I need to bake it, but unsure how to proceed.
I managed to present a picture, to be clicked for loading, but takes forever to load and until all the file is loaded nothing happens and I'm not sure how to solve this. Check it here:

First, I would recommend to use the JSON format (see this tutorial, you need method #2).

Second, try to decrease the poly-count of your model.

Thank you, Yuri!
Much appreciated.
