Roll-wagen will do R1...

I've worked out how to mount the bogies but before I cut plastic and commit I've taken the chance to pick up a couple of R1 curves from my parent's home to check if the Roll-wagen could cope.

On paper it looked possible and I'm pleased to announce that although it's exceedingly tight, it does just go round.

Result! Although in normal use it'll only see R2 as a minimum it's nice to know I can use it without restriction.
