Hello
So I'm building this for the first time so apologies for the dumb questions.
I have built exactly as per book and spent an hour last night double checking etc. I have everything where it needs to be.
Firstly, when I turn the front drive shaft, the rear wheels don't spin at all (orange arrow)..when I spin the shaft manually behind the red casing (blue arrow), the rear wheels and front wheels spin...in different directions!
