Gary,

For sure the rpms are high, but as I mentioned in a previous post, much of the noise comes from the prop blades chopping the air off the wings, the 3-blade having half as much blade to chop a ...

Best I can say is that our highly regarded Jabiru dealer has one on his plane and sells them also, as well as selling Jabiru props. As I mentioned in previous post, I haven't followed what Jabiru is ...

Gary,

I haven't followed lately what Jabiru is saying about wood props, but our local dealer is using a composite Sensenich prop on his Jabiru plane. Sensenich thoroughly tested them for use on Ja ...

No Pat, not me.

Hi Jerry,
just a long shot but are you th ...

Another way for reducing pusher prop noise, though I'm probably
repeating myself, is to go to a 3-blade prop instead of a two. Much
of the noise comes from the blades chopping the disturbed air ...

Pat,

FWIW, there are many of us flying in front of and behind the Jab.
Prop length makes a huge difference in noise in the pusher
configuration. Though not quiet, my 58-inch prop in a pushe ...

John, no disagreement with you here about the difference between a
Kolb and a Titan. Was just responding to an imprecise, unqualified
statement. Like I've said previously, wish I still owned b ...

Rick,

I appreciate your informed input. I can't speak for Jabs/Rotax 4-cycle engines on Kolbs, but I can on Titans. The arguments from both sides, I've found, change nobody's mind, typically g ...

Wellllll, there are some of us who would disagree that the 912 is vastly superior...and that it provides much better performance.

FWIW, over many years and many planes, I've yet to see a plastic tank
that hasn't developed bulges with time--just like a few of us.

..well, if you're concerned about weight, as some have noted, haven't seen the ramp-checkers walking around with scales, but that's not to say they couldn't.

John,

As always, thank you for your photos and other input. You do good by
showing how much fun and adventure a person can enjoy flying light-
sport type aircraft, Kolbs in particular--of co ...

Terry,

Not that he needs it, but I endorse Mike's thinking on NOT using a
wooden prop on a Kolb...or any pusher for that matter. I and several
others hereabouts have spent a fair amount of money rep ...

Yeh, it's great...and exciting...if not expensive to start a
propeller collection. Got a few meself, some remnants from having
turned a few into toothpicks. Had a 3-blade Warp on an 618-powere ...

Guys,

Some of our local pilots used these adjustable needles, but none are now, perhaps because we don't hear about them anymore. One pilot had an engine-out and off-field landing because he adju ...

John,

I strapped 35 lb of lead in the nose of my 503 DCDI Firestar, which
always seemed like a waste. Now I see it might have been. Two of my
Firestar flying friends have nothing, which mad ...

Thanks guys for ideas on how to avoid carrying around extra freight
in the nose. And, John, don't recall now who at the factory I spoke
with about their carrying extra weight in the nose. It w ...
