TOMARK AERO VIPER SD 4 Rotax 912S gear ratio 2.43 |
DURANDAL-3
Hello to the team,
What an exceptional propeller! I reach 235 km/h effortlessly with a takeoff in less than 130m. We have measured several times. Impossible to reach that with the old propeller. It's amazing how changing the propeller changes the performance so much. I would never have believed it if I had not tested it myself. I am satisfied and I will not give you the propeller back :-)

We changed the DUC propeller we had on our Viper for an EPROP. We are very happy with the results. The finish of the EPROP blades is magnificent.
