Jumbo,

Obviously it's not going to be an exact 747 nor do I believe you intended
to have an exact copy of a 747 so on that note, I really commend your vision here.
Looks like it's going to be a whole heck of handful at first but real fun after the kinks (if any)
have been worked out.

Did you say 4-Li-Po's and ESC's? Where will you be placing the other 2 batts?

Either way...NICE WORK and have fun!
