Umm, the engines will push it forward. The engines act on the air, not the ground. The wheels spin freely and have NO power to them. You understand this, correct? It's the same as if you are on a treadmill with roller skates and you strap on a jetpack to push you forward.

Better yet, stand on a treadmill and have a friend pull you with a rope. That rope = jet engines
