The 3-blades model DURANDAL is one of the most popular model of the E-PROPS range. Since 2010, hundreds are flying in all over the world, providing a great pleasure to their owners. See the CUSTOMERS FEEDBACK


There are 8 different sub-models of DURANDAL propellers, depending on the engine (Rotax 912, 912S, 914, 915), reduction ratio, diameter (from 155 to 180 cm), use (speed, cruise, STOL, tow). Any time it is a different blade geometry, in order to have the exact propeller adapted to the aircraft, the engine and the use. The DURANDAL-R model is specially designed for towing use.




Each DURANDAL 100-R propeller is delivered complete and ready to be mounted with :
- All screws (inox 8.8, Nord-Lock washers)

- An aluminium black anodized flange for tightening

- The 6 Rotax drive lugs for centering (price = 32,5 € without taxes, included in the propeller's total price)

- If necessary, the extended hub which replaces a spacer.

See page EXTENDED HUBS ISS. Option offered : again a major saving !
- The digital protractor, to adapt the pitch, very precise (price = 75 € without taxes, included in the propeller's total price)
- The Instruction and Service Manual of E-Props propellers, updated version.

See it here : MANUALS
- The identification sheet of the propeller with ref number, max RPM, recommended first pitch

1/ Comparative tests on WT9 tow aircraft (April 2016) - COMPARATIVE VIDEO


The 3-blades E-PROPS propeller ground adjustable pitch
- is lighter (gain 9,5 kg)
- less expensive (gain 3 879 €)
- with a 6,5 time higher TBO
is significantly more efficient than the 3-blades variable pitch WOODCOMP

2/ Comparative propellers tests made on WT9 Dynamic Club SD tow aircraft (May 2014)


Between :

- reference propeller : composite 3-blades ground adjustable pitch (DUC WINDSPOON)

- E-Props Durandal 100-R propeller : carbon 3-blades ground adjustable pitch


Result : with the E-Props, rate of climb is better of more than 30 % against the reference propeller


* Test report dated 17/01/2007 : Dynamic with reference propeller

* Test report dated 20/05/2014 : Dynamic with E-Props propeller

3/ Comparative : DURANDAL-R with 2-blades variable pitch propeller


End of 2013, a comparative test has been done between two propellers for tow planes :

- 2-blades composite variable pitch, Ø 172 cm, weight 8,6 kg

- 3-blades carbon E-PROPS DURANDAL 100-R ground adjustable pitch, Ø 180 cm, weight 2,8 kg


Characteristics of the 3-blades E-PROPS compared with 2-blades variable pitch :

● better efficiency : + 29 kg of static thrust

● lighter : minus 5,8 kg, to respect the max MOI of the ROTAX engines (6000 kg.cm²)

● less expensive (see PRICES)

● easiest to manage in flight

● without maintenance

● MTBO : 2.000 hours


E-PROPS : better than a variable pitch propeller !


The DURANDAL 100-R has specially been designed for tow aircraft
