JUANITA STERN WHEELER
This part took a bit of improvisation and patience, but here’s how I approached it:
Step 1 – Making custom tube holders
The kit didn’t include the M2 screws for the tube supports, so I had to make my own.
I used some brass rod from my stash and soldered a small washer on top of each piece.
After painting them, they actually look better and provide a larger holding surface.
Step 2 – Preparing the brass tubes
Next came the tedious part—bending two pieces of 300mm brass tube
(2mm OD, 0.5mm wall thickness).
To make this easier, I annealed the tubes:
Heat the brass until it turns red
Let it cool naturally
This makes the material softer and easier to bend without kinking or cracking.
Step 3 – Bending the tubes
Once annealed, I carefully bent the tubes to shape.
Very delicate work considering how small the tubing is—take your time here.
Step 4 – Painting and routing
After bending, I painted the tubes and routed them through:
The E2-10 horns
The back splash
The bottom of the motor shaft holder
Not an easy task, but doable with patience. (pictures 6-7)
Step 5 – Securing the tubes
Once in place, I installed my custom hold-downs at the rear rudder assembly to secure everything.
Step 6 – Creating the cable guide system (improved setup)
Now comes the good part.
You’ll need to bend two smaller tubes at a 90° angle so the cable can pass through and meet the servo cog tracking ends.
The kit includes small nylon guides for this, but honestly… that setup didn’t work well for me.
So I made my own:
Instead of 2mm tubing, I used 3mm brass tubing
Much easier to bend
Allows the cable to pass more freely (here I use my own cable, just a bit thinner and runs very easy in all the bends.)
I then used some scrap wood to build a small support block and glued the whole assembly to the superstructure wall, making sure it aligned perfectly with the steering servo horn.
Step 7 – Reinforcing the rudder linkage bar
The bar that connects both small rudders didn’t look strong enough to me, so I scratch-built a new one using square brass tubing.
Much stronger and gives a more solid feel to the whole system.
Final thoughts
This whole setup required some trial and error, but in the end it works smoothly and feels much more robust than the stock configuration.
