Well Most people would probably mount the servo in the front of the model with a single connecting rod from the servo the the rear of the model. I did that kind of thing in the John Deere 9560R, you can get the idea in this video it's just missing the connecting rod. As for the electronics you need to decide if you're going to use existing RC components or build it all from scratch like I do.

Just starting this post to let people introduce themselves and let us know what kind of radio controlled vehicles they are creating. I'm an engineering student from Ireland and I've mostly been working on creating a radio controlled tractor so far. The model I'm using is a SIKU Massey 8680, I used servos for drive and steering, I added LED lights and a XBEE radio transceiver all controlled by a PIC 16F627. I've started work on a tip trailer as well as turning a ROS Hitachi 210 into an rc model so I've plenty to keep me busy.

Hii Stephen, welcome to the forum. It would be great to see some pctures of your JD build, what components are you using?

Afternoon Oisin, William here, I have been following your youtube video's and blogs, and I want to have a crack off building my own RC tractor. I have a old radio controller from an Nikko racing car could I use this, it operates at 27 MHz. I have bought the list of parts you have listed to convert the Fendt tractor.

Hi Willie,
Well if the receiver in the car was small enough to fit in the tractor I don't see why not or you could replace the electronics in the controller with your own. That's how I made my first controller.
So you bought an XBee radio module? It's very good, I have so many models I needed to switch to a cheaper radio, you might have seen in my more recent videos I'm using an NRF24L01 so you'd need to modify the newer code to work with the XBee.
What tractor are you going to convert?

Evening Oisin, I was going to try the Fendt until I saw you video saying the John Deere was the best to start with, the electronics part of the build is way over my head, most of the items you listed I had to google to see what they were. Not really sure what to do now, then I was looking at the Kane trailer, it looks simple to start on, if you follow your conversion will a Siku factory RC tractor tip it. If you are selling kits I would definitely buy them from you. I posted a comment on youtube under the name Loughfield so you can ignore it. Thanks for the replies. O I tried buying a Fendt back axel with a motor could find one, looked on your suggested links any other places I could look.

Yes the John Deere is the simplest build to start with simply because it is so big which gives you space for larger and stronger servos and things like that. In the John Deere build I use a Tamiya 70189 because it's easier to get than the Siku motors but it has plastic gears which can break and it's not as smooth as the Siku motor. Have you tried ebay.de for the siku motors, if you search siku control on the german ebay you usually find more parts there.
The Kane trailer is simple but I still need to do some work on that. You can just add a radio module to the trailer and use a second controller to control the trailer if you want to use it with your siku models, you'd just miss out on the light controls but that's not a big deal.

Is it easy to write the code, what type of equipment will I need

No the code is easy it was designed for students with no background in engineering or programming. Basically the designers wrote a program that takes the simple commands in your code and converts it to the real code for the microcontroller. It just takes a little practice.
For an arduino pro mini you just need an FTDI cable or a USB to serial device to program it, that's all really.

That's not a stupid question, it's in fact a very good question. I do have bread board like that, wires like those and a power supply module like that and they are very useful. Having a few bread boards is handy, I have lots of different bread boards because I found I ran out and so just kept buying them until I no longer ran out. You're probably better using the battery for power rather than the power module because it's regulator can't deliver power as fast as the battery so you might get weird performance and struggle to figure out why. There isn't much else after that, I have arduinos and motor drivers with headers soldered on which I just use for testing i.e. I plug those into the breadboard but use different modules with no headers in the final tractor, it's just easier during testing.
You'll need your tools, soldering iron, thin solder, snips, small pliers, screw driver, knives and tweezers are always useful. And of course a multimeter to measure voltages and currents, without that it's almost impossible to figure out why something isn't working.
