I'm having trouble figuring out how to drill 3/8in holes to run the flex tube through the fuse. It's too long. Is there an easy way to do this so I can steer my tail wheel?

Just run it (tube) down the side of the opening that is available. It's a flex tube, and the only difficulty you will have is getting the line up at the exit. I just used a straight wire from the the rudder servo to the rear, through a slightly elongated exit a few inches in front of the tailwheel. Here is the thread with pictures from my Alpha, I also have an LT-40.

I forgot to add, if you need a long drill bit, it is called an Installers Bit. They are kind of pricey for using only once or twice a year.

I think that rings a bell. Like the one to run wires in your walls at home.

Thanks,

Why not just run a "normal" pushrod, made from dowel and two pieces of pushrod wire? That way, you only have to drill 1 hole at the rear of the fuse for the pushrod to exit. Run it through the center of the fuse formers where the big holes are.

There is another option for a stearable tail wheel.
You could purchase the type tail wheel that uses springs attached to your rudder.
Or you could purchase a long drill bit.
Hope this helps.

On an LT-40, you would have to modify the rudder to get it to extend below the elevator for the type with the springs to work. That was why I stuck the thread link in on modifiying my Alpha, where I used a solid wire down the middle, in a tube, and where the exit was, the hole is slightly elongated to compensate for a "slash cut" or diagonal cut of the tube, flush with the exit. I have one that uses the spring from the rudder to tailwheel on my Tiger 60 that I built as a taildragger. It is heavier than the LT-40, and the spring setup takes the load off the servo on landing.

no need to "drill" a hole, just cut one out with your blade. Here is where my hole is located on my LT-40

I have had excellent luck with a VERY simple solution. I ran a wire through the fuse and horiz stab, direct to the rudder.

I used a standard steerable tailwheel mount, but made my own wire/spring assy. I drilled down right at the rudder hinge point and ran a wire straight through. This way in addition to the spring for flexibility under load, the wire up through the fuse give it torsional flexibility. The reason I like it is - it looks good and clean, it has no external horns or cables to catch or break and it is just so simple. Once I figured it out it just took me a few minutes.

I can explain a little more in detail if you give me a PM.
