I found what i was looking for about the gear shift timing on the winner sport
ORIGINAL: andyb178
there's a hole at the front of the small cog hold that cog still, then rotate the larger cog you will see the bearing inside the small cog turning, keep turning until you see the adjustment screw which you can adjust with a Allen key. This shortens the shift to second gear or holds first gear longer depending on how you want the car set up.
I though i read it somewhere, i must have got confused about the allen key screws
