When I last built an Airfix Roland many, many years ago, I thought it was one of the best of the crop of Airfix WWI offerings. Returning to WWI aviation many years later, I have picked up the vibe that the kit is so bad that it is not mentioned in polite society - or at least serious WWI modellers. I now have the Wingsock Datafile and at first glance that reputation seems a trifle unfair. What exactly is wrong with this kit please and is it easily rectifiable?
