Converting the PAL-V ONE from airplane to automobile is a very easy process which takes about 10 minutes. Once the engine stops, the propeller folds itself automatically into the driving position. Pushing a button then lowers the rotor mast into the horizontal position. The same motion lowers the tail. The outer blades are folded over the inner blades via hinge mechanisms. The last steps in the process are to push the tail into its driving position and secure the rotor blades. This conversion can be executed by the driver/pilot after just a short training lesson. To convert from driving to flying mode, simply reverse the sequence.
