andythenorth - I would guess thats my problem too. I was just hoping that I may not have to take the whole thing apart to sort it out as that was one of the first bits that gets built. Im building the B model. There seems to be three spindles next to each other which all lock together using a cog and that seems to be jamming it all up. This is a photo with the motor in-situ showing the three cogs that I was talking about; This is a photo of the same section without the motor

I have had a go at making my first Techic Kit 42008B however when I try to activate the motor it appears to jam up and then nothing happens... I'm just hoping that it's not one of the first bits that got built, right in the centre that's the problem as it will mean pretty much starting from Scratch. Do you have any specific advice for this set or any generic advice for troubleshooting this type of problem please?
