A ram air turbine has turbine blades (18) connected to rotate a transmission shaft (26). The transmission shaft is connected to drive a first gear which is engaged to drive a second gear. The second gear is connected to rotate an output shaft extending through a strut (22) away from the transmission shaft. A governor arrangement is configured to change a pitch angle of the blades in response to speed, and includes counterweights (29) acting on a spring (38) in the governor arrangement. The governor spring is positioned on an opposed side of the strut relative to the turbine.
