    Sven is not a member of this forum but he's my friend and as we build the rig together I'd like to share some photos.

    He uses the same linear actuators as I do for my bigger two-seater. The actuators look a lot shorter than those we can usually see on rigs built like this. But the reason is their better stroke to total length ratio. If we would add, say 200mm of empty tube where the motor is located normally it would look the same.

    Interesting base idea. I had thought about doing that "3 spoke" approach myself, but not sure why I talked myself out of it. I guess I was thinking it would come across as less stable, but after thinking about it some more I'm not sure it would. You still have the same hinge line between any two points, regardless of whether you have material there or not.

    Worst case I just planned to bolt my rig to the floor anyway, so wouldn't even matter a lot in the long run.
