Rudder Assembly Type II

This type of rudder assembly is used by Guylain, it is easy to make and effective. With only a few modifications it can be converted to a twin rudder, the following instructions are for a single rudder.

Material Required (for 1 rudder system)

• 1 brass tube & 1 brass rod(approx 1/8" diameter, rod to fit perfectly in tube)
• 1 piece of aluminium to make rudder or use a cheap 1" paint scrapper
• 1 square 1/2" dowel
• 1 aircraft nylon steering arm for 1/8" shaft
• 1 tube 5 minute epoxy
• 15 minutes of your time

This is an example of twin rudders using this system of rudder assembly(picture from "Project Tippy").

Parts Preperation

• Cut a piece of dowel to the lenght of 2", drill hole 1/2" from the end the size of the brass tube
• Cut brass tube 3/4" long
• Cut brass rod 1 1/2" long, and cut 1/2"slot at the end of rod
• Cut the shape of the rudder in the aluminum , to simplyfy i used a paint scrapper blade(1"x4")

Putting the Puzzle together

• Epoxy the dowel to the rear of the boat sticking out approx 1"
• Epoxy the tube in the hole of the dowel, with equal ends sticking out(this creates the bushing for the rudder to turn into)
• Slide the rudder into the slot cut into the brass rod, align it to be the most accurate possible and apply some epoxy( i drilled holes in rod and tip of the rudder to add more grip for the epoxy)
• Then slide the rod into the tube then screw on the steering arm over the shaft.
• Verify that everything rotates smoothly and then you are ready to attach the servo linkage.
