What type of constant speed prop set up are you talking about? Who is the
manufacturer?

Constant speed props are used on VERY FEW Jabiru engine installations. I
think the reason might be that the gain in performance is not worth the
large expense of the prop. We did try a three blade Air Master prop with
Warp Drive blades on an Esqual back in 2003 and found that we lost 12 mph in
cruise from the wood prop we had used on it. We could get great climb but
no matter how much pitch we added the cruise speed was not up to the
performance of the wood prop.

Nick, I am trying to come up with a combination tie down point / jack
pad. The access to the wing is thru the bell crank hole which is 98"
from the fuse. I would expect to have 400 lbs. on the jack pad and was
wondering if the spar would support that weight in that area. How do
you now support the plane for service of a tire or gear ? Your input
would be greatly appreciated. Tex

Hi Tex,
Let me jump in here and suggest that you will probably need to provide
Nick one additional piece of info for him to be able to figure the actual
forces you are talking about. That additional info is - how are you going to
use
the jack points? What I mean by that is will you only use one at a time to
raise just one main wheel off the ground, or do you intend to pick up the
complete airplane by using both wing jack points and a tail stand? If you are
only gong to lift one main wheel and leave the other main wheel and the nose
wheel on the ground than you don't have a 400 pound load near the area of the
aileron bell chank.
So far I have seen no need for a jack point as there are two simple ways
to pick up one wheel for maintenance. One way, just have someone get under
one wing (on their hands and knees) out about mid span or more and push up
under the spar. When they have the main gear up, place a padded crate (or saw
horse -something to hold the wing up) so your buddy is not on his knees for
too long a time. The other way, is to find a small scissor jack (like came
with the older Corvettes) that will actually fit under the main gear leg bottom
fitting and just jack up that wheel. I have also used a floor jack but
sometimes I need to air the tire up a little to get the floor jack to fit under
the lower gear leg fitting. I have used all of the above procedures on both
Lightnings and Esquals with no problems.
But your idea of having a jack point in each wing will certainly come in
handy when you are doing landing gear retract test. ;-)

Buz

Another way is to use a cheap ATV jack. They go down flat and lift fairly
high. You can always put a box with padding on top of it to increase the
height. I found one used for $35.00.
Here's a link to what they look like.
