The transmitter. |
 |
Here it is all together. Gives you an idea of the size of the transmitter. |
 |
I've cut a piece of copper clad board and drilled two holes for some brass wire. I could have used copper wire but I had this on hand and the proper size. Two holes in the board for the brass wires. The other two are 00-80 tapped holes to hold the whole works down and a insulation gap file in the board to separate the minus from the plus. |
 |
The board is fastened to the floor of the crane and is ready to have the positive and negative voltage wires attached. |
 |
View at the back of the crane. |
 |
I fabricated a couple of .010" thick pieces of shim stock with a slot in them to solder the wires to and using a 00-80 nuts bolted the wires in place. |

When I first wired up the Rx I had no idea which outputs do what so I just hooked them up. I had to rewire all three motors. Here is a picture for those that might follow this thread and build an R/C crane. Here's a picture of the hook up to the reciever. |

The trucks are to be put together with metric screws, 2.2mm X .45 to be exact. Even I don't have a tap that size. Mine are all imperial. What to do? Guess it's time for a little soldering using the resistance soldering rig. But first the trucks need to be prepared. A bit of filing to clean them up and the bearing holes need to be drilled for the ends of the wheel sets to fit into. So here are the pictures. Drilling out the end bearing holes. |
 |
One side soldered in. Make sure the insulated wheels are all on one side. |
 |
Soldering in the second side |
 |
The roll test to make sure all wheels are free. That's why the picture is fuzzy. |
