Hi Kit
No Need to be Sorry, that's why the Topics stay here, so they can be reopened if needed..  ^^^ :wink1:

I say that its not a good idea..! does not mean that you can not do it that way, it means that there might be some fall backs..
depending on the throw of the Servo and the positions of the linkages between Servo and Rudder.

what can happen:
when driving astern, and a full (hard left or right) rudder command is given one or both of the rudders can go past the Servos throw point, which means that the rudders would turn round and face the wrong way... thus giving you no control over the ship any more...
I hope I have written this so it is understandable...

this happened to me once in my boating career, since then I connect my Servos to rudder with double linkage.. see my builds

Thanks Colin, very clear - I will have a think.  I never go flat out astern except to take way off in case I swamp it but you can never foresee what you will may have to do to avoid a collision....

Cheers
