... That does sound a touch excessive.... :unsure: (I think Adobe is full of it...) :D

So, I'm going to put one of my upcoming projects on hold for a bit (I'm waiting on motors anyway...) and tackle a fully redesigned 200 Scale Sparrow. I gave the design a quick look today and I'll probably make the nose detachable. Twin motors, I'm going to use cheap chinese 2212s I have laying around (Should be PLENTY of power)...

Sorry guys it was my fault what I wanted to get the dwgs out quickly and they were not sized correctly for printing in Adobe Reader. I use Adobe Acrobat and there I can crop and print. Its could have been more pages lucky it was only 72. Enjoy your build if you have any problems I will correct my dwgs to any request, still learning CAD. Enjoy

When you are increasing the size of the Sparrow you might not want the original dihedral as it was designed a 3 channel "V" tail. Some builder are now adding ailerons which would reduce the need for large amount of dihedral.

At 150% the center section just fits on a sheet of foam board (within my laser cutters working area)… I might turn it into a polyhedron a wing with just a touch of dihedral on the wing tips with ailerons.
Thoughts?

I think it will work great!
