Angel Interceptor scale model 3D print model

Lovely model and I like the modified split. However, the original single part I first downloaded could be easily scaled as it had a full length. The new split does not and is a different scale to the original model posted. I can get close to an end-to-end measurement just checking the lengths of the main parts in the slicer but there is still a bit of guesstimation as the tailplane overlaps. So can you please advise the scale of the parts you currently provide so I can accurately rescale it? Thanks.

nice design
