Still building but had to comment (on the great set of cores received from Crist) before the plane is finished.
Accuracy/when compared to print is right on, quality of the cuts and packaging are super!
Delivery time as promised.
Thanks Crist!

Yep, Crist makes some outstanding cores.  He just finished a project for me and hand delivered them to me at the St. Louis contest.  Now I can't guarntee that he will hand deliver for you; however, I can guarantee that they are good quality, accurate, and affordable.
