see http://www.indiegogo.com/gary2g for the full-size VTOL project using this control technology (but with propellers, not giant LPs!).
Using the gyroscopic and inertial properties of spinning discs for control. Of course propellers produce these dynamic moments too, in addition to - and faster than - conventional thrust changes, and are what give bicopters better response and stability than fixed-motor ships like quadcopters. also see http://www.gressaero.com
