Hello Glyn,
I have no personal experience of this kit or others from the same maker, but have only ever heard good things about them.
I have also had a good look at the kit instructions as available on the Aero-naut website (**LINK**), and must say that it looks like a well thought-out and complete kit, with thorough and well-illustrated (and properly translated!) step-by-step instructions.
It is a rather unusual kit, too, in that, although the hull is built on frames, the main building material is laser cut ABS plastic, with most details made up from etched metal.
