This evening I made a start with taking the model apart. This went surprisingly well. I have converted a Bruder tractor into a RC model, and I have to say that the Bruder models are put together really well, better then the Britain one. I have already seen a potential problem, the mast is really narrow at the end, and I'm worried I'm not going to be able to fit a servo in there. Below is a photo of the model taken apart.
