How accurate or the die cut pieces compared to the drawing? Im trying to pin this thing together but some pices are slightly smaller, bigger etc etc. It also looks like they changed some of the parts compared to the drawing. I look at the sheet with all the part locations on the balsa and they're name so I know I have the right pieces they just dont match up. What really bothered me was the Stab platform has a hole in it for the the rear of the fin but compared to the drawing it is about 1/8" inch off. Is it possible the kit is diffective or is this common?

Thanx in advance.
