Abstract
A self-propelled military type land vehicle with a power take-off friction coupling in the form of a rotating cannon fits into and is retained in a helicopter shell with the power coupling driving the helicopter rotor. A releasable latch carried by the helicopter retains the vehicle within the helicopter shell and in driving engagement during simulated flight. The helicopter has a hand grippable depending tail support with a trigger disposed near the support for effecting release of the land vehicle and disengagement of the power take-off coupling from the rotor without braking the rotor.
