Lynn, how does your prop withstand rain? I was told that wood props are not very good at that. My Jabiru wood prop is still okay but I fly very little in rain and if I can't avoid it, I always fly at low RPM.
This leads me to change the subject of the title and ask you all: how do you fly in rain? I mean, beside the fact that visibility is very reduced, what are your experience with rain?
I ask because we have a very wet summer here in Norway and I have already cancelled two fly-ins because of the rain.
Cheers,

I've flown in rain only about 4-6 times, and that was minimal rain.
Just a brief little shower, so visibility wasn't all that bad. My
leading edge is showing signs of very slight pitting, but I attribute
this to mostly the sandy dirt conditions that you get on some grass
strips. This pitting I refer to is like the edge was hit with a
sandblaster...pitted but smooth, but not polished any longer like
when it was new. I'm going to check with the Sensenich folks at
Oshkosh next week and see if their new composite ground-adjustable
prop is out of flight testing yet...it is for the Jabiru and Rotax
engines.

Michel -
The rain will remove the leading edge of the prop given enough time.
I flew mine in moderate rain for about 20 minutes and found the finish
at the tips was pretty well pitted. It would be just a matter of time to
do real damage. I think flying in the rain because you have to get
through it is probably ok, but I would not intentionally fly in it with
the wood prop.

Michel -
My Sensenich has a translucent tan leading edge. As I recall it is some
kind of Urethane (but not 100% sure). I flew mine in a pretty solid rain
once, and after the flight I noticed it felt rough and looking at the
urethane it looked like it had been sandblasted near the tip. I got some
clear protective tape from the auto parts store for use on the hood of
a car for protecting from stone chips. I flew with this for a year wrapped
from the leading edge to about 40mm back on both front and back sides
over the urethane. This flew a couple time in light rain and held up well.
After about a year it started coming loose so I peeled it off and now fly
without.
My conclusion is that the wood prop can handle rain, but you'll need to
to keep it recoated as the water will definetly strip the finish from the
leading edge out by the tip pretty quickly.
I thought about laying on a layer of glass cloth at the tip along the leading
edge using West System epoxy as a sacrificial layer that could be
periodically sanded off and replaced if need be. Never did do it, but it
would probably work.
Regards,
Jeff.

Lynn,
The Sensenich ground adjustable composite prop has been out for a while now and is being used quite a bit. I know a guy in Colorado has one on a IV with the Jabiru engine and is quite pleased. I have seen them on about 3 Jabiru aircraft and I am told Jabiru is having to induce drag to keep the airplanes Sport Pilot legal. I bought one from John McBean, so if you want one, go get it now!

Really? Their website says the Jabiru and Rotax ground adjustable is
currently undergoing flight testing....maybe they haven't updated
their site, and I haven't called to inquire, either.
Are any of the 3 that you saw the 2200 engine?
