=> DATA SHEET

- E-PROPS : the world's lightest propellers
- Very small Moment of Inertia
- 100% carbon, RTM Manufacturing process, Helical Continuous Fibers
- Electronic balancing
- Titanium leading edge protection
- ASTM F2506-13 standards / TBO (inspection) : 4.000 hours
- ESR Effect : near from the behaviour of a variable pitch propeller


KIT for RV-12 :
- Propeller = Carbon Hub + Carbon Blades with Titanium leading edge protection
- Carbon spacer, if necessary : : back 10 mm (brings the spinner of 10 mm closer to the reducer flange)

- Screws (standard)
- Special full-carbon spinner for RV-12 with central hole for pitot passage, diameter 250 mm
- Pitot tube passing through the spinner : ADU-6 adapter
- Digital Protractor (handy to adjust blade pitch)
- Protection covers for blades in Neoprene
- Propeller Identification Sheet, with first recommended pitch (25°)


OPTIONS (extra cost - see Accessories) :
- Titanium Screws : saves 115 g (on the 3-blade version) and to check the tightening of the screws from 100h to 200h.
- Rotax drive lugs changer (the assembly of the E-Props V20 range is done without Rotax drive lugs)


Customer feedback :

We recently replaced the standard Sensenich 2-blade prop on our RV-12 with a 3-blade E-Props.
+12 KTAS and increased climb performance but that was not the end... the SMOOTHNESS was unimaginable, it feels like you're sitting in a jet or driving on a smooth highway.
I was blown away. In our case it worked spectacularly and was extremely worth it.

E Prop received and installed on our RV-12. We have compiled some key statistics before and after the installation for your review. Smooth and improved performance.

I got an E-prop for my (Rotax 912ULS) RV-12 last summer to replace the original 2-blade Sensenich. I was primarily interested in reducing vibration, since the E-prop blades, hub, and spinner are dynamically-balanced at the factory. The first thing I noticed was the smoothness and lower noise. The initial pitch setting from the factory is definitely for max cruise speed. I ended up dialing it back one degree for better-than-stock climb with a 7 kt increase in cruise. E-props offers a money-back guarantee, but I'm keeping the prop.

I fitted an E-Props propeller to my RV-12. I'm absolutely delighted. Much better performance than the Sensenich, lighter, less vibration, quieter, and so much prettier.

I have done a couple of test flights now. Your prop does a very good job. Climb and cruise performance are much better than the original Whirlwind 2-blade.
It also beats the DUC Swirl-3 propeller by 3-5 kts cruise efficiency and 100-200ft climb performance.
Well done !

I got around to installing the propeller and dialing it in on my Vans RV-12 and I love it! So far it has proven to be an improvement over the previous Sensenich.
If I may make a suggestion for high altitude customers: I ended up with a prop pitch of 23.9* vs the recommended starting pitch of 27*. I would recommend that customers living at or above 4500’ MSL start at 24*. I recorded data during my climb and cruise from 4473’ to 14,000’ MSL that I can provide if you are interested.
Thanks for the outstanding product and incredible craftsmanship.

Just to let you know that we have fitted and flown with the new Eprop on our RV-12 and so far are very happy. It did catch us a little with the pitch settings as it behaves differently to my previous propeller. It seems to have this almost magic property to provide good take off rpm and cruise rpm.

I am extremely satisfied with this carbon three-blade propeller on my VAN'S RV-12 with Rotax 100 hp engine.
I gained 10 kts of speed. The takeoff is very short.
Thank you for this propeller of a great quality and with really excellent performances.
P.G. (2023-05-02)

We did that RV 12 prop install and the pilots were amazed. Ultimately we picked up 200-300 FPM climb and 6-8 kts in cruise. They loved the smoothness more than anything.

E-Props on VANS RV-12 : 15 MPH gain !
