The essence of the algorithm is that you spin in the horizontal plane. If you have enough power your single remaining motor can create a vertical airstream that will keep the altitude constant. The limit on spinning is the structural integrity of the system with all that angular momentum, the limit on flying is the frequency response of your control system.
A number of people have built and demonstrated so called 'half prop' helicopters based on the same principle. If you have ever seen an maple seed fall you can understand the principle, search for 'maple copter' on Youtube for some videos of them in action.
