The Wind-Up Chicken Express

I made some lightweight cars for my wind up engine. On my current track (comprised op 2 loops from an old 9v set) it will do the following:

 

by itself: make one lap

with one car: almost a full lap

with two cars: little over half a lap

 

I have ordered a loop of this old style track as I beleive it will give it better traction than my 9v track does.

 

I experimented with different tires and these worked out best (offset tread pattern)

 

However, the tires are loose on the wheels. I think I may sand them to rough them up and give the tire more grip... maybe even a small dot of super glue just for maximum track adhesion

 

I'm hoping to make a clever mini layout based entirely on this engine and possibly adding some other wind-up fun to it as well!
