Hello Guys
I’ve been working in the hardware. Here in México, there are few places to buy hardware and fitting, the most are for airplanes, I only know one decent store who sale things for boats, but is too far away, so sometimes I have to do those things myself. That’s the arms case, I had to build them both using 1/8” collars and 0.9 mm brass and the results work well but I think the next time could do it better
Here I send you a picture of the rudders hardware with the servo
As you can see in the picture, I found the advice of a marine expert
Best regards
