RGR

I intended to buy the early BR version but noticed that a recent magazine review stated the crane is recommended for 3rd radius curves or greater. I contacted my preferred supplier who confirmed this is the case, but the model may negotiate 2nd radius, although there could be de-railing problems. I wasn't prepared to risk spending over £200 on a vehicle that might well not run on my layout (2nd radius minimum) so I won't be buying one. A great shame, as it clearly is an excellent looking model; but it's got to work as well. Has anyone out there had problems with running the crane on less than 3rd radius curves?
