PC-14: 



The Perry built PC-14 (belonging to Texas 

 A&M Univ.) (now TECHDIVER) is propelled 

 by a 36-VDC, 7.8-amp, reversible General 

 Electric motor. Motor speed control is by a 

 selector switch on a portable control box 

 which provides three speeds forward and 

 three reverse (Fig. 8.29). The rudder and bow 

 planes are controlled by port (for dive planes) 

 and starboard (for rudder) levers which are 

 manually operated and are linked by a rod 

 and cable to the plane and rudder, respec- 



tively. The cable controlling rudder move- 

 ments (manufactured by Controex Corp. of 

 America, Croton Falls, New York) is made of 

 stainless steel and consists of a flexible hous- 

 ing in which a flat rod rides on ball bearings. 

 Control mechanisms for the larger Perry- 

 built vehicles consist of hand-held portable 

 units (Fig. 8.30) which control all motor 

 speeds, direction and position (for trainable 

 units), the planes and rudder. The portable 

 control box may also include an automatic 

 piloting feature. 



STAR III: 



STAR III receives thrust power from a 7V2- 

 hp electric motor (110 VDC) and vertical and
