I've already started construction on both of mine, but if you want to clone one there a few options
1) I created openrocket files for the main fuselage and pods that I used actual measurements and weights on last year. It should get you pretty close as far as the form of the 1250 goes (i gave up on trying to simulate flight correctly, only wanted to make it clone-able and ready for upscale), especially since decals are not a requirement.

2) The accur8 vinyl guy sells a wrap for the 1250. Along with the wrap are instructions on how to clone the bird with card stock patterns.
hope that helps! feel free to pm me if you have any questions!
