145 to 152 mm translates to 5 1/2" to almost 6 inches from the LE NO WAY THAT COULD be right ! no way that model would even fly ......as previously suggested go with 25 % wing cord closest to the fuse , I am sure you will find a great diffrence in the numbers , let me know I just got mine haven't really done much with it other then do an inventory of the parts , kit looks pretty good so far , post some pic of yours I would love to see it completed
