Just wanted your thoughts on this. I'm getting the feeling that a lot of people are going with the dual-axis thing in a very specific way: Mount an altitude-rotating platform/arm on azimuth-rotating plate. Now, this may be the simplest to conceptualise, but what about removing a bit of clutter?
I was thinking about all the gearboxes and such, and then I had this flash of a MacGuyver episode where a blade keeps swinging left and right across the room. So, inspired by the Macs, this is what I was thinking of:
(just very quickly put together in a couple of minutes, don't post a "ACTUAL SIZE" sticker on it)
Instead of having most of the weight of the gear rest on the axe where one of the engines would be, why not have most of the weight supported by a stronger system, and the the altitude move by a motor around the curvy part of the support.
Again, the picture shows a full-solid support, but this could be made in quite a few different ways. Just wanted to know if you had considered other designs that the ones currently in use.
