Off-board gyrocopter take-off systems and associated methods are disclosed. A representative method includes restraining a gyrocopter from vertical and lateral movement, pre-rotating a fixed-pitch lift rotor of the gyrocopter via a power source located off the gyrocopter, and releasing the gyrocopter for vertical movement to allow the gyrocopter to lift under a force provided by the lift rotor. Optionally, the method can further include interrupting or reducing power from the power source to the gyrocopter as a way to release the gyrocopter for vertical movement.

1. A method for operating a gyrocopter, comprising: restraining the gyrocopter from vertical and lateral movement via at least one restraint;releasably coupling a transmission device between the gyrocopter and an off-board power source;pre-rotating a fixed-pitch lift rotor of the gyrocopter via the power source and the transmission while the transmission, power source and restraint are fixed to a portable base;releasing the transmission from the gyrocopter; andreleasing the gyrocopter for vertical movement to allow the gyrocopter to lift under a force provided by the lift rotor. 2. The method of claim 1, further comprising interrupting or reducing power from the power source to the gyrocopter. 3. The method of claim 2 wherein interrupting or reducing power from the power source to the gyrocopter reduces engagement forces between two elements of a transmission system coupled between the power source and the rotor, and releases the gyrocopter for vertical movement. 4. The method of claim 1 wherein releasing the gyrocopter for vertical movement includes actively removing a vertical restraint on the gyrocopter, in addition to interrupting or reducing power from the power source to the gyrocopter. 5. The method of claim 1 wherein releasably coupling includes coupling a female spline element and a male spline element. 6. A method for operating a gyrocopter, comprising: restraining the gyrocopter from vertical and lateral movement via at least one restraint, the gyrocopter having a body, a propeller, a first power source coupled to the propeller, a lift rotor, and an on-board transmission portion of a pre-rotator, the on-board transmission portion of the pre-rotator being coupled to the lift rotor and having an on-board coupling;releasably coupling an off-board transmission portion of the pre-rotator to the on-board transmission portion of the pre-rotator via the on-board coupling and an off-board coupling, the offboard transmission portion being coupled to a second, off-board power source of the pre-rotator;operating a controller, coupled to the second power source, to direct power to the lift rotor; andreleasing the on-board coupling from the off-board coupling. 7. The method of claim 6 wherein releasably coupling includes coupling a female spline element and a male spline element. 8. The method of claim 6 wherein restraining the gyrocopter includes engaging a wheel of the gyrocopter. 9. The method of claim 6 wherein restraining the gyrocopter includes engaging a skid of the gyrocopter. 10. A method for operating a gyrocopter, comprising: positioning a restraint of a pre-rotator to at least restrict vertical and lateral motion of a gyrocopter, the gyrocopter having a body, a propeller, a first power source coupled to the propeller, a lift rotor, and an on-board portion of a transmission device coupled to the lift rotor, the on-board portion of the transmission device having an on-board coupling, the transmission device further having an off-board portion coupled to a second power source of the pre-rotator, the off-board portion of the transmission device having an off-board coupling; andoperating a power coupling, coupleable among the lift rotor, the first power source, and the second power source, to selectively couple at least one of the first and second power sources to the lift rotor. 11. The method of claim 6 wherein positioning the restraint includes engaging the restraint with a skid of the gyrocopter. 12. The method of claim 6 wherein positioning the restraint includes engaging the restraint with a wheel of the gyrocopter. 13. The method of claim 6 wherein selectively coupling includes selectively coupling the on-board transmission portion to the off-board transmission portion. 14. The method of claim 13 wherein selectively coupling the on-board transmission portion to the off-board transmission portion includes releasably coupling a female spline element and a male spline element. 15. The method of claim 6 wherein operating the power coupling includes coupling the second power source to the lift rotor to pre-rotate the lift rotor. 16. The method of claim 6 wherein operating the power coupling includes coupling the first power source to the lift rotor to pre-rotate the lift rotor. 17. The method of claim 6 wherein operating the power coupling includes coupling the first power source and the second power source to the lift rotor to pre-rotate the lift rotor.
