Now that is realistic!
My Bachmann Lyn seemed to handle R1 curves alright, just looked a bit odd with the overhang
Mate of mine brought his around to run on the Taita Gorge Railway, which is famous for its R1 curves, no problems whatsoever.
Actually, thinking about it, there was an issue with the chopper couplings and R1 Curves, I ended up taking the chopper bit out and using a chainYebbut was it fitted with Accurcaft choppers fixed to the buffer beam?
I think the OP's concern is that with fixed couplers on the beams, the overhang may prove too much on R1's.
