Sorry for that.
The Ford Trimotor apparently used the Gottingen 386 wing section at the wing root.
It looked like this red line.
Which is similar to what you have on your model so it is more or less true scale.
However it is a very thick high lift wing which is why Ford used it, however it does work at all well at small sizes, very small in your case.
Not in anyway a criticism, I was just pointing this out.
Your plane will certainly fly but with its scale thickness wing not as well as it might.
"Shockie" is a class of small highly aerobatic indoor planes that make full use of foam construction and electric power. The are usually entirely made up of simple flat surfaces and look something like this.
.
I hope this helps.

Thank you for all your assistance. I really could not have got through this endeavor without your help.
One last question: the rubber is 25 inches but the plane only 8. How much of the rubber do I use? And is there an optimum location
at which to tie the knot joining the 2 pieces of the rubber? Thank you.

I'm not an expert, but, I would tie with a Reef knot, double it = 12.5" and put the knot behind to peg dowel at the rear. Pull the nose block out until the rubber is straight. By the time you've put a few turns on the rubber shortens very quickly and pulls the nose block onto the plane.
Using rubber motors is very much a black art, Paul should be able to help. Use a bit of Press stick to hold the prop and nose block on, then do some test glides in long grass, it's easy to throw too hard! The glide should be controlled and not nose up or down. When it comes to putting power on, just try a few turns at a time. If you have no side thrust on the nose block, the plane should climb and turn left. The experts use nose block thrust and rudder to give a climb in one direction and glide in the other.
There are ways to get more rubber in, using a bobbin for example, but that's way above my pay grade.

sadly me experience with rubber power is very limited, built a keil Kraft 109 when I was 12 and a 1/2 size Wakefield a year or so ago...neither where spectacular fliers, if you use face book there's a couple of groups ( Eric and I are both members of the keil Kraft group) there are a lot of guys there with far more knowledge than me..

if you are calm and collected when all about you are going berserk - you've missed something important!

But my KK models are the big r/c ones, not the little free-flight ones.
I did build their Luscombe Silvaire - but it flew like a housebrick! (Probably my fault, not the model's!)
