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

'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 by 3-5 kts cruise efficiency and 100-200ft climb performance.' (20-08-2024)
