RE: B-36
Wrangler,
the choice of electrics is a good one. I'm not an electric guy but the technology is definitely there. A guy in our club has an electric B36 at 80 inch span. A very reliable flying plane. No engine out problems.
I can tell you from my experience that, if you want a forgiving flier, keep the wing loading down to 2 pounds per square foot or less. 1.5 would be wonderful. At your proposed size you have about 10 square feet of wing so aim for 15 to 20 pounds. At that weight and wing loading, .25 size glow motors would fly it fine.
But most of all, " Strategic Air Command" with Jimmy Stewart is required viewing for anyone thinking about the B36 !
