For those interested, there is no engine connected to the blades while in flight. Most gyros have is a linkage called the pre-rotator with a clutch that you engage while stationary on the ground. This allows you to get the rotor to about two thirds of the speed needed for take off at which point you release it, and then do a take off roll to build speed and rotor speed.
