Well in my downtime building the 2.2 Snarky from Apogee I decided to sit and see if I can come up with a design for a 4" version. A true upscale would put the airframe(s) at 4.434 or close to 4.5" so I settled on a 4" version instead. The only thing with this design I have to work out is the exact size of the wings and stabilizers and nose cone. The sizes that are in this ROCKSIM file are exactly 2x the original kit.
Is there a formula to use to get the exact dimensions? What if you found the percentage difference between the two different sized airframes and decreased the wings and stabilizers by the amount, would that give an accurate scale size for a 4" model? Since I could not find a nose long enough (unless anyone knows where get one about 20" in length) I decided to go with balsa.
