A flight control system includes a lift control algorithm which selectively communicates with the pitch command of the flight system control algorithm. The lift control algorithm selects the proper control commands to coordinate an effective transition between hover and forward flight. The most efficient vehicle pitch during transition is thereby automatically generated so that sufficient lift and control throughout the transition between rotor borne and wing borne flight.

The paper roll dispenser of claim 13, further comprising a control module operatively coupled to a motor means for dispensing paper from at least one paper roll, said control module including a first switch adapted to control the length of paper being dispensed by said motor means. 15. The paper roll dispenser of claim 14 wherein said control module further includes a second switch adapted to set a time delay between successive paper dispensations by said motor means. 16. The paper roll dispenser of claim 15 wherein said control module further includes a third switch adapted to vary the resistance value of Rtrim for adjusting the sensitivity of said proximity detector. 17. The paper roll dispenser of claim 13, further comprising means for visually guiding a user's hand toward said proximity detector, said means including a pseudo-button disposed within a sunrise-like setback on a cover for said paper roll dispenser near said proximity detector. 18. A method for dispensing paper towels, comprising the steps of: (a) providing a carousel assembly adapted to support a first paper roll over a second paper roll and to rotate about a first axis defined between said first and second paper rolls, each of said first and second paper rolls having a core; (b) providing motor means for dispensing paper towels from at least one of said first and second paper rolls on said carousel assembly; (c) providing a proximity detector adapted to trigger the dispensing of paper towels by said motor means when a user's hand is positioned w
