Here are my results on my Zephyr:
PA: 26 at 4800 rpm
PA: 27 at 5500 rpm
PA: 24 at 4300 rpm
tiered
4000 rpm : 180 km/h
4500 rpm : 210 km/h
4800 rpm : 225 km/h
5000 rpm : 240 km/h
5500 rpm : 260 km/h
Max in beam: 5600 rpm : 265 km/h
Decorating distance almost identical to the wood-comp but with the E-Props I gain in climbing and cruising speed of 20 Km/h with the same engine speed.
