Sensenich Metal Props

Fixed Pitch Metal Props Specifically for RVs

Description

The Sensenich metal propellers we sell were developed specifically for the RV series and are the ONLY fixed pitch metal propellers approved by Van's Aircraft Inc. for use on RV aircraft.

Propellers from production aircraft are not suitable, and unfortunate experience has shown that modified production propellers can fail without warning with deadly consequences.

Because the metal prop is not as thick as the typical wood prop, a different spinner front plate is required.

NOTE: 70CM (150/160 HP) PROPELLERS ARE LIMITED TO MAXIMUM 2600 RPM

Use the charts below to choose the proper propeller. Start by determining the length of crankshaft spacer required by the cowl in your Finish Kit. Kits shipped since late 1993 include the short cowl (shown on the packing list or inventory sheet as C/S) which uses a 2 1/4" extension. Prior to 1993, cowls for fixed pitch props used long cowls (shown on the packing list or inventory sheet as Fixed Pitch or FP). This uses a 4" spacer. You must also choose the diameter of the prop bolts required by your engine, and the horsepower rating of your engine. New 160 hp engines from Van's use 7/16" bolts, new 180 hp engines use 1/2" bolts.Prop pitch recommendations (in parentheses on the chart below) are based on cruise speeds for RVs equipped with gearleg fairings, landing gear intersection fairings and Van's Pressure Recovery (PR) wheel fairings. Cruise speeds for RVs with older wheel fairings (narrow cross-section w/ brake blisters) will be 5-6 mph slower and require a prop with approximately 2" less pitch. A rule of thumb: 1" of pitch change equals about 25 rpm static and about 30-40 rpm at full throttle cruise.

Here's how to decode the part numbers: PROP 70CM7S9-0 (81) means: 70 = design diameter in inches, CM = designator for O-320, 7 = bolt diameter in 16ths of an inch, S = requires crank spacer, 9 = length of spacer in 1/4s of an inch, 0=full length blade (not cut down) (81) = pitch in inches. This prop is suitable for a 150 hp RV-3 or a 160 hp RV-4, using a 2 1/4" spacer and requiring 7/16" crank bolts.

Price includes extension and mounting bolts.

Determine the pitch required for your aircraft from the chart below:

............Aircraft...........Horsepower.....Required Pitch

  • RV-3.....................150/160..............(81)
  • RV-4.......................150...................(79)
  • RV-4.......................160...................(81)
  • RV-6/7/8..................150..................(78)
  • RV-6/7/8..................160..................(80)
  • RV-6A/7A/8A/9A......150..................(77)
  • RV-6A/7A/8A/9A......160..................(79)
  • RV-4.......................180..................(85)
  • RV-6/7/8..................180..................(85)
  • RV-6A/7A/8A...........180..................(85)

Currently the The Sensenich metal propellers for the O-360 that have part numbers starting with PROP 72FM8S(xx-x) are NOT CERTIFIED, and are considered an EXPERIMENTAL prop.

The Sensenich metal propellers for ALL of the O-320's ARE CERTIFIED propellers.

If a new propeller and an Experimental Lycoming engine are ordered at the same time, Van's can offer a special "package" discount on the combination.
