Does anyone know if there is a thread or pics somewhere of this set-up?

There is no thread for this set up. It is one of a series of experiments that I have been working on for a couple of seasons. I hope to do an article on it soon. Until then it is being monitored, written up and photographed as I see how it holds up for a season.

There are several versions. This is my latest and is different from its predecessors in that each half is adjustable.

The concept is that the horns contain ball bearing, not the clevices. The T-bar is connected to an unsupported pushrod that is connected to a servo that is mounted on its side.

Regards,

Eric.

Eric, What is the T bar made of and how is it connected?
