Alright, this is very easy to do, and it makes him look a LOT better. Basically, you unscrew the piece holding the two halves of the back together, gently slide off the head piece, put the clear part back (make sure it's in the same position!) and then you can put the head inbetween the two wheels, like usual. But this time, you can turn it around, so that it's in the place where it should be! However, this means that you'll have to either remove it or put it inside the hood everytime you transform him. Still, I think it's worth it. Oh, you can also remove the doorwings for that added bit of accuracy, but I personally think he looks better with them.
