Default New 300-72RV Series? Constant-Speed Composite Propeller from Whirl Wind Aviation

(Note: “New” refers to April 23, 2019).../a moderator

Whirl Wind Aviation, has developed a new 3-blade composite constant speed propeller, the 300-72RV Series™, for Lycoming (Lyc 0360 - IO390) powered Van’s RV style aircraft.

Whirl Wind Aviation is now taking orders for and delivering the new 300-72RV Series™ constant-speed propeller.

The 300-72RV Series has been several years in the making, and performance results have been very good. Pilots have noted an increased take-off acceleration, and an increased rate-of-climb with the same top speed as Whirl Wind's legendary 200RV Series™ propeller.

At just 36 lbs, the new 300-72RV Series™ propeller is the lightest weight constant speed propeller in its class. Most impressive is that it's a 3-blade propeller that is 5 pounds lighter than Whirl Wind’s 2-blade 200RV Series propeller due to the 300 Series' optimized and compact design.

In addition to weight savings, the 300-72RV Series™ composite propeller offers ultra-smooth operation and lower cockpit noise levels. The 300-72RV Series™ proprietary blade design features a patented carbon fiber X-core™ theormoset composite construction with an electroformed Nickel leading edge for superior erosion resistance and FOD protection.

The 300-72RV Series™ constant speed propeller will accept most pressure to increase pitch governors, and is suitable for the Lycoming 0320 / IO-360 /IO-390 types of engines that can operate a hydraulic control governor/propeller. Diameters available range from 68” to 72” for the 300-72RV Series propeller.

Carl Statin, Naval aviator and RV-14A (IO-390) builder / owner, said, “I couldn’t be more impressed with my WhirlWind 300-72RV Series composite propeller. Since installing the new 300 Series prop I’ve noticed a pleasant improvement in operational smoothness and a definite lower cockpit noise level. After rotation on take-off, accelerating to 90 knots, I was able to maintain 25 degrees nose-up attitude until starting my turn down wind. I would not have believed I could do better than my previous WhirlWind 200RV Series – but they did it with this new 300 Series™.”

He added, “When I fly with other pilots, I always get comments on the smoothness of the WhirlWind propeller. And it looks sleek and sexy sitting on the ground too.”

Available for order through Whirl Wind Aviation, the introductory 2019 list price is $12,500 (includes the propeller and 13” RV style spinner). Order lead-time is estimated at 4 weeks for standard blade colors which include a gloss carbon fiber finish with white tip stripes, or white blades with red tip stripes, or a gloss or semi-gloss black with white tip stripes.

Default 300-72RV Limited to 200HP

I inquired about this prop for my -14 build after i read the announcement. I received an email back that cautioned me that 200HP was absolute maximum HP to suit this prop. They went on to say that if my IO-390 puts out more than 200HP, then i should go with the 300-74RV which was designed for 200+ HP engines. I am planning dual electronic ignition so certainly the output will be more than 200HP. Its a shame as this seemed like a nice option - given this limit not sure how many -14s would be in a position to utilize this prop.

Default Order vs lead time

I love the concept but concerned about the lead time. 4 weeks is awesome but one post is still waiting since August. That's unacceptable. Maybe I missed something.

Somebody help me out here...

The first paragraph says that the 300-72 series is for O-360’s and IO-390’s.

The sixth paragraph says the 300-72 is for O-320 through IO-390.

The first paragraph indicates O-360 and IO-390. Not IO-360? But the sixth paragraph says O-320, IO-360, and IO-390. Not IO-320? But yes to IO-360?

I’m confused.

Apologies if it was not clear to you, the new 300-72RV Series is suitable for the full range of 4-Cylinder Lycoming engines configured for a hydraulic control constant speed propeller - which includes the O-320 up through the IO-390 type engines. Fuel injection is not a factor for suitability of this propeller.

If you have a question about the 300-72RV Series' suitability for your specific engine and airframe, please feel welcome to call or email us anytime for clarification.

To be clear:

The reason it was not clear to me or anyone else is that your posting was inconsistent with itself as I spelled out in my post.

Your opening ?Sorry it was not clear to you? is condescending and suggests that there?s something wrong with my reading comprehension skills. Not exactly the way you win customers.
