Propeller Speed Reduction Units (PSRU's) are also part of the Firewall Forward product line. The CAMDRIVE 500 PSRU, is designed to handle up to 500 hp.
The design and and build up of this unit is the result of years of hands on experience dealing with PSRU's by both Butler and Wilson. Adapters are designed to fit the Chevrolet V-8 blocks being used by many builders of the Fighter Escort Wings Mustang, Lancair IV and IVP, Express, Piaggio, replica warbirds, and others.

Features:
- Helical cut gears mesh continuously for smooth power transfer, extended life, and quiet operation.
- The gear case is cut from 7000 series aircraft grade aluminum billet stock by a CNC machine. Billet stock allows precise load carrying capability calculations not possible with castings. It reduces weight and provides maximum structural integrity to overcome gyroscopic precession forces.
- Optional fail safe coupling absorbs torsional harmonics. The coupling provides both torsional damping as well as a fail safe connection to the PSRU. If the torsional material in the coupling were to fail, the coupling would still allow engine torque to be transmitted to the PSRU.
- Lubrication is by dry sump system independent of the engine. Internal oil galleries eliminate the need for external oil lines.
- The gears are cut from an extremely tough alloy developed for heavy equipment and therefore does not need to be heat treated. As a result, the possibility of tooth chipping is virtually eliminated.
- The nose cone is in compression while the attachment studs are in tension.
- The gear case is also in compression with studs in tension. Two of the studs carry through from the front plate to the block.
- Two power take-off points on the rear of the case are driven by the output gear.
- The output shaft is drilled for hydraulically controlled propellers.
- Optional accessory drives (2)
- Optional custom bell housing assures perfect alignment and has pads for forward engine mounts.
The CAMDRIVE 500 Propeller Speed Reduction Unit is a key part of the power train for the Fighter Escort Wing's Mustang.
