4D model skill level index (This is not a scientific matrix, it’s more of a feeling.)
This is a relative reference for crafting skill on each 4D model. This subjective reference is based on the construction steps needed for the model, the crafting skill needed and the readiness of test fly adjustment. (discussion in "choosing your model")
paper airplane designs for the DIY project. List from easy (Rating 1) to a more complicated model (rating 10)
3.5D model (the partial 3D models, for relative easy fly adjustment)
Rating 1 (Good for the 1st 4D model)
