Default Whirl Wind 300 Series Constant Speed Prop on RV4 and RV10

https://www.youtube.com/watch?v=BI9Ts4pGyag

Had some fun making this video of our 300 series 72" propeller on a Van's RV-4 with Lycoming O-360 Straight Valve engine. Also included some ground footage of the 300-77" on a Van's RV-10 with Lycoming O-540 Straight Valve.



Check out the 300 series constant speed propeller: the lightest propeller in its class! Get better takeoff performance, higher rate of climb, smoother operation, and no compromise on top speed

Best Applications:
300-72" (36 lb): RV- 4, 6, 7, 8, 9, 14
- Engines: (I)O-320, 360, 390
300-77" (42 lb): RV-10
- Engines: (I)O-540 Straight Valve
Whirl Wind's newest propeller, the 300 series comes in 70-79" diameters ranging from just 36 lb - 42 lb with spinner and hardware included in the weight.
