I'm not sure about the Ocean Star but... Although it would work to some extent on Red Eagle, it would not be able to give you a full 360 degree turn on a VSP, (unless someone knows different, )
Hi All, your quite right Dave M, i'm in the final stages of testing azimuth controls that I've built using 360 degree potentiometers and they do work well with the red eagle it gives you full 360 turning ability but as you say the azimuth vessels ocean star and Bugsier 2 they will not work with.
If these two vessels had the same steering paramiters of the red eagle instead of their current limitations the controls would work great and I'm guessing that you would have the same problem with the Ship control unit.
I'm in the process of making a short video to show these controls in action and the limitations with azimuth ships.
If it were me I'd save the money and spend half on building your own controller and the other half on wine, Spambot and the next two releases of shipsim, thats a lot of dosh!
