jabiru 3300 or 912

So much for needing a 6' prop for short field performance, huh?

Jab sure does make a nice looking little motor, too. Best of luck with it.

My friend in a Model 3 ordered the same Tennessee prop that I used but what they sent performed much differently. He could not get his takeoff rpm up past 2700 however he passed VNE at 2800 cruise setting.

He returned the prop and they trimmed it apparently because it had the same numbers. This time he could get 3250 on climb but a much slower cruise speed. Now he has to carry 100/200 more rpm to cruise with my plane.

His plane will get off the ground much faster than mine. When I soloed it I was surprised on how quickly it would get off and climb rate was 150 fpm better than mine.

My point is that you can prop for short takeoff or climb or cruise. LSA prohibits in flight adjustable props so for me the Sensenich which is a 64x36 is a better overall prop on the Jab if I really wanted to do a lot of short field work. I can get in and out of a short - soft strip in the desert (500') with either prop.

From my experience the planes with very short cabability cannot cruise with me.
