Cool. Thanks guys, I like that tape idea, though I could see the modeling clay flattening out over time and throwing them off balance again.

Yeah aqwut, it would make the system more efficient with a cone at the rear, too. But if you only have one cone, it's much better to put it up front to optimize the intake suction. Turbulence in the exhaust actually helps because it creates a higher pressure behind the vehicle, which in turn creates more efficient thrust.

And please be patient. I can't make a video until I finish the project! LOL
