Vance....In the FAA rules it stats that a Gyro can't have variable pitch rotor blades, if you do you need a different permit that is hard to get I was told many times.
Perhaps you are writing of the limitations for a sport pilot Frank.
A Sport Pilot, Rotorcraft-Gyroplane pilot is limited to flying a gyroplane with a two bade fixed pitch teeter rotor. See (9) below.
Private Pilot, Rotorcraft-Gyroplane has no such limitation that I am aware of.
14 CFR 1.1Definitions
Gyroplane means a
rotorcraft whose rotors are not engine-driven, except for initial starting, but are made to rotate by action of the air when the
rotorcraft is moving; and whose means of propulsion, consisting usually of conventional propellers, is independent of the rotor system.
Light-sport aircraft means an aircraft, other than a helicopter or powered-lift that, since its original certification, has continued to meet the following:
(1) A maximum takeoff weight of not more than—
(i) 1,320 pounds (600 kilograms) for aircraft not intended for operation on water; or
(ii) 1,430 pounds (650 kilograms) for an aircraft intended for operation on water.
(2) A maximum airspeed in level flight with maximum continuous power (V[SUB]H[/SUB]) of not more than 120 knots CAS under standard atmospheric conditions at sea level.
(3) A maximum never-exceed speed (V[SUB]NE[/SUB]) of not more than 120 knots CAS for a glider.
(4) A maximum stalling speed or minimum steady flight speed without the use of lift-enhancing devices (V[SUB]S1[/SUB]) of not more than 45 knots CAS at the aircraft's maximum certificated takeoff weight and most critical center of gravity.
(5) A maximum seating capacity of no more than two persons, including the pilot.
(6) A single, reciprocating engine, if powered.
(7) A fixed or ground-adjustable propeller if a powered aircraft other than a powered glider.
(8) A fixed or autofeathering propeller system if a powered glider.
(9) A fixed-pitch, semi-rigid, teetering, two-blade rotor system, if a gyroplane.
(10) A nonpressurized cabin, if equipped with a cabin.
(11) Fixed landing gear, except for an aircraft intended for operation on water or a glider.
(12) Fixed or retractable landing gear, or a hull, for an aircraft intended for operation on water.
(13) Fixed or retractable landing gear for a glider.
