Radio Control Throttle Box

construction sign

I got interested in controlling trains with radio control, but I didn't like the airplane controller,

so I searched for a better controller. I finally came to the conclusion I needed to design my own

custom built R/C throttle box. This is how I went about it.

The airplane controller in my left hand. Thumb on the throttle stick.

If you are switching cars and using your right hand to set turnouts or uncouple manually you can't reach the other stick to reverse direction.

The NCE Power Pro Cab06 is great but you still can't reach the reverse button with one handed operation.

construction sign

The NCE power Pro is also great and the reverse button can easily be reached if you use your right hand for

uncoupling or throwing turnouts, but if you switch hands again this will be difficult.

I searched the net for a company that sells project boxes and came up with these VM-Seires Project boxes.

You can order the rubber boots for a better grip. They come in the three colors shown.

This is the Vm-24. I'm using my hand for size comparison. This is with the boot off.

All three sizes with the rubber boot cover on.

They also come in two variations. The one's I got have a 9 volt battery compartment. They also come with a two AA battery compartment.

To start with I needed a pc board to hold the components. I used a perf board to get the shape of the area. Once I have the components in their final place

I will etch a circuit board for easier installation

construction sign

I needed some small N.O. switches for the binding circuit. An old TV with front push buttons severed the purpose well. /P>

construction sign

I mounted the switch on two wire wrap posts soldered into the perf board. Drilled a hole in the end and glued in a

piece of plastic tubing. A piece of plastic rod and a small pad glued on the end to make contact with the button.

construction sign

Plunger installed.

Front panle with plunger installed.

construction sign

I didn't like the looks of the plastic plunger so I made one out of brass.

construction sign

Assembled and installed. Much better.

These are the seperate parts for making a custom reversing switch. Brass bar with

channel milled in, pc board, two micro switches, and a activation lever.

construction sign

The two micro switches and the back side of the pc board with 8 #61 holes.

construction sign

Switches mounted in board.

construction sign

Soldered and mounted in body of reverse switch.

construction sign

Opposite side showing slot for operating lever.

Operating lever temporality in slot.

construction sign

Approximate location of custom lever.

construction sign

Custom lever screwed down with two 0-80 screws.

construction sign

Both top and bottom covers cut out to clear lever and lever shortened.

construction sign

Final postion without rubber boot.

construction sign

With rubber boot.

construction sign

I didn't like the nub of brass sticking out the side. I thought a nice looking bat style lever would look better.

I found that in these mini bat lever toggle switches. Just pry apart and the parts fall out.

construction sign

These are the parts you'll need.

construction sign

Lever assembled on end of actuator.

construction sign

Looks much better.

construction sign

Even better yet.
