Wow! Now that looks great! I have built models since I was a kid. Built a 3ft wing span covered balsa ME-109 at eleven. That was in 1965. I have built other things. For instance, I built a TriCorder from Star Trek Next Generation with all the lights blinking, etc. Made it from a block of wood and when finished it looked just like the one on the show. It was for my son. I made the panels with graphics and labels for the buttons. It was fun. I am from a family of designers and inventors, my dad and brother have several patents.

I worked with them building some of the patterns, jigs, etc. myself. Saying that only to let you know that I have some ability to create some of the scale stuff myself.
I have been building and flying my own planes all this year. I haven't gotten perfection in mind yet on the current one shown below. I am using it to practice making what ever I need. I built this one (the red plane, not the glider

) from my on design, complete from scratch and it flies great. It's has a 55inch wing span and weighs 27oz. I use a brushless electric motor with lots of power to spare.
I understand completely what you are saying, I just did not want a plane so big that I could not display in my home office easily. I may need to start with the small one with less detail first and then proceed with the larger one. I do appreciate your input.
