The Siku Control 32 motors which you get in the Fendt 930 model are great but they are hard to find and shipping is usually expensive. If you have any suggestions about where to get them let us know.
I have bought them from Modellbau Schulte before which was a little difficult as they don’t appear to have a little difficulty with English. But once you get round that you will have a good selection of parts to choose from. There is however a fairly hefty shipping charge and a charge for paying via paypal also.
A better option may be to visit the German ebay and search Siku Control and scroll down through the items for sale until you see what you want. That way you are protected if the part doesn’t arrive. Click here to view the search result on ebay.
