RE: Double the engines?

I concur,

My original track was a single #35 roller chain system and I had a lot
of trouble with thrown track, I am in the process of building new track
out of Double wide #40, I am also installing new wheels and track guides
because, as Tyng says, the track guiding system at the wheels is very
very important when turning.

About bike chain jumping of the sprockets.  I think it may have more to
do with the sprocket than the chain.  If you look at the typical bike
sprocket you'll see one tooth that has a ramp cut into it to allow the
chain to come on and off easily.  I always wondered if a standard 40
series sprocket (same pitch as bike chain but thicker) were turned down
to an appropriate thickness, if that would work well for a sprocket
drive track.

No matter how a track is driven.  If it doesn't have a good system to
keep the track in alignment at the road wheels.  It will most likely
fail in a skid turn.
