Title: Bow rudder
Post by: rickles23 on December 22, 2017, 02:37:43 pm

Hi,
I need to put in a bow rudder which is a simple job.


But the bow and stern rudder servo connection is giving me nightmares.


So what I need is a way to:
The bow rudder when not being used is locked off and the stern rudder operates.
The stern rudder when not being used is locked off and the bow rudder operates.
Regards...

I have an additional bow rudder on my HMS Polyphemus, as per the original torpedo ram.
You will need to fit a servo reverser Y lead as the bow rudder turns opposite to the stern rudder.
Frankly, just like the original ship, it is not very effective in practice, but was intended more for withdrawing after a ram attack..
In the end I disconnected the Y lead reverser and had it operating on a separate Tx stick channel, which gave idependent control in low speed maneuvering. If you are building a reversing ferry with separate prop and rudder each end then separate channels will give you either / or operation.
