I think that you've done really well to get a bare chassis, without the benefit if a weighted body, to run that smoothly and with good track holding. Congratulations!

Just one thought. I might be wrong but on very close observation, immediately after reversing, it looks as if the coupling rods go slightly out of line near the top of their rotation. It might just be an optical illusion or something needing a slight tweak?

 

Dave.

Apart from me not shaving the crank pin retainers enough, and the coupling rods 'possibly' being a wee bit slack...

 

No, I think your right.  They are a bit slack I think, but this is my 2nd ever working chassis and when it (finally!) runs this well I'm reluctant to tweak it yet.

 

 

Thanks for the comment.
