Subject: | Re: Aileron hinges and sagging |
Craig,
In the late 1990's, along time ago now, I visited Kim Prout in LA to see his
project while building mine #294.
His father was present that day helping him. He used to work for McDonnell
Corporation as , I think, an aerodynamics and he recommended having a 3rd
hinge on the ailerons placed closer to the inner mass balance from the mid
point. I have done this without any problems and certainly strengthens the
aileron.
Europa brought out a MOD to incorporate an extended tail wheel for better
control. On installing this he also recommended strengthening the hinge
attachments to the rudder by doubling the length of each hinge. Another good
idea due to the added forces on the rudder with the steering tailwheel.
All the best with the build,
Cheers,
Tim

There is a scheme out there to cut down the centre console (examined by the
factory - perhaps Andy D can enlighten...) - we looked at the loads imposed
by the engine on the centre console in relation to the taildragger
attachment structure, and found them negligable - but didn't look at the
flight loads. I agree with GS - keeping the centre console for
crashworthiness is a good idea...

Jim & Craig
forgot to mention in my last remark, don't put the third hinge in the
middle for resonance reasons. Vibration will be damped with the hinge
off centre

Hi Paul,
I cut my center console down. I was told at the time to keep it at least 2"
above the forward portion of the seat bottom where it turns down into the foot
area. I did put some reinforcing plies inside the tunnel in this area. So
far, 118 hours, with some of those hours spent yanking and banking, and no
sign of any problems. Contact me off list if you'd like some photos.
Hope it helps!

Subject: | Autocad drawing of XS mono |
I believe that this question has been asked before, but does anyone
have a good Autocad drawing of the XS mono. I have made one, but trying
to reproduce it from the little drawing in the manual makes me suspect
it's accuracy. I am down to trying to fit a ULPOWER 260i engine in the
drawing. I have generated a pretty accurate drawing of the engine, since
their site has drawings of it laid out on a grid,which makes copying
easier. If anyone wants my XS drawing, they can have it with the caveat
that it's accuracy may not be good enough for critical fits.

Subject: | Re: centre console |
We cut this console down but added several layers of bid to reinforce
the inside. We then created the top with 5 layers of bid. It's secured
with #10 screws and nut plates. The left seat was widened by reshapeing
the left side of the console to allow for more leg room. This was done
with 3 layers of bid over a center of 1/4 inch foam shaped to allow a
right leg more room. As you can see it makes a great arm rest and a lot
more room for toys. The fuel filters are located right under the arm
rest and can be viewed in flight anytime.

Subject: | Out rigger latching postmortem |
Hi all,
As some of you may recall I had an incident where my port out rigger
didn't latch. I did some work on it this weekend and discovered that
the head of a castellated nut had been catching the side of the W21
outrigger plate.
If you look at the drawing on the bottom left hand corner on page 9-23
of the manual you will see that a AN4-11 drilled bolt passes through
the top of the outrigger leg OR1 attaching it to OR4. The AN4-11 bolt
is fitted with a AN310 castellated nut.
What happening was that there was enough play where the bolt goes
through the OR4 latch arm to allow OR1 to twist sideways so that the
nut catches on the side of the W21 outrigger plate.
What I did was to shorten the AN4-11 drilled bolt by 2mm and use a low
profile castellated nut, I believe that they are designated AN320 (not
certain). In addition I fitted another AN960-416L washer in the slot
of OR1 to take up the slack between it and the OR4 latch.
All seems well now, but I would encourage everyone to take a look on
the inside of there W21 outrigger plate to check for signs of
catching.
I intend to fit a micro switch to detect gear down and locked, but I
am afraid to say the the ultimate solution will be to convert my
aircraft into a conventional tail dragger. Another instance of the
outrigger not locking or the main gear over center lock failing is
more than I would want to contemplate at some remote airstrip.
Regards, Paul

Paul/All,
I've noticed that my hard copy build manual calls for a total of 2
AN960-416L washers in the OR1 slot, whereas the latest online manual
has ADDED a 3rd washer. Checking my installation, there appears to be
sufficient slack to add that 3rd washer.
Thanks Paul for bringing this to our attention.
