You said that it WILL clear the treadmill, so you admit that it will move forward. Well, given a long enough treadmill (typical runway), it will gain speed and lift.
I hate repeating myself, but what the hell........
I just want to make sure you're still insisting it will fly off the treadmill........

Sure, it will move forward if full throttle power overcomes the speed of the treadmill, but it needs sufficient LIFT under its wings to fly, which it will NOT have if its barely going 5-10mph.
Why is this so difficult for you to understand?
Lift is required for a plane to fly. Forward motion at a high rate of speed (all relative to the size, weight, and wing angle/size of the plane) are what allow it to CREATE lift due to air passing under its wings. So then if the plane is on a treadmill, how is lift provided for it to take off? Again, it is NOT a helicopter or anything rocket powered that ascends vertically. GET IT?
