I have one of the GM Plastics Mooney kits. I have heard it is the same plane as the Tri R, but can't confirm that. Anyway, the plans are in 4 sheets and quite detailed, but no formers except for a couple right at the nose are included. The fuse is composed of many, many presawn former parts, similar to the old Royal kits. The cabin top is a large clear part, maybe 9" wide with an internal formed plastic "headliner". Here are a couple of shots showing the fuse construction to give you an idea of how it goes together. The plane could be built from top and side views, but it would take an awful lot of drafting and interpolation.
