Hello Michael,

I have a Europa XS with a 3300 installed swinging a Sensenich hollow carbon, ground adjustable prop and it has been flawless fo over 89 hours now. Very well made prop and hub, very light and very smooth. Performance is excellent. My numbers are on the high side of what Europa quotes for a 912S/Warp Drive combo. Airmaster is supposed to release an electrically adjustable hub for this blade set later this year, probably at Oshkosh.

I have no experience with the Prince P-tip props, though.

Hope it helps!

Regards,

Hi John,

I would be shocked if your Jabiru didn't outperform a Rotax 912S on nearly any airplane. For one thing it has 20 or 30 percent more horse power.

I have heard rumors that the Sensenich wood props actually outperform the composite ones. It would be interesting to hear from someone who actually tried both on the same airplane and could actually compare the results.

Happy Landings.

Hi,

Have you ever tried DUC props? Do you believe in more than 65% real eficiency? I'm flying a Pioneer 300S with Jab3300 and a DUC prop with 64in. Got to be careful not to reach VNE at 160 Knots. Takeoff? Less than 300 ft! Climbs at 1900ft/min at 80Knots (BRC). Cruises at 125 Knots at 70%. 14L/h Unlead 98 oct.

What you say?

Best regards.

Miguel

Miguel,


Those numbers are most impressive indeed. 300 ft run, 1900 ft/min. 80 kt
seems a bit high for best rate of climb. Alpi states something closer to
65 kt.
Do you really mean you're close to 160 kt at WOT ? In that case, 70%
cruise should be closer to 140 kt ?

Hello Gilles,

Most Alpi Pioneer 300's flies with short wing versions and ROTAX 912S, as Pioneer Team flies. About prop eficiency, it's not linear. Pitching prop with different values did seam to be linear as well. 160 knots can be done with high energy, that means, pitch down the bird at about -250 ft/min at full. In 3 o 4 seconds you're there. Level out and keep full power. 125 Knots at 70% 'cause larger wings induce more drag and better lift

Understand. Makes sense.
Thanks,
