well I don't know which one it was that did the trick but it works now. I manually worked the gears and that moved the stabilizers so I turned it back over to notice that the connection to the top of the battery box wasn't fully pressed down on one side. After this it all works. One very pleased Dad and one even more pleased Son. Thanks again for all your help and advice. Tony.

Thanks 'TheItalianBrick' but as this is my first big Technics build I'm not 100% sure what you mean. Any chance you could give me an idea what pages of the instruction book I should be looking at. Mine has the one big book not the seperate ones. Thanks again for help as it's just doing my head in.

I was wondering if anyone can help. Just finished building the crane but stabilizers don't seem to work now. I did check them at the point where I was supposed to and they worked fine, but now I've finished, the boom and hook work properly but now stabilizers won't move in or out or up and down. Any suggestions would be greatly appreciated. Thanks.
