Hi Steve

As far as flying with a higher than 1370 AUW and adjustments to CG here is some
info I uploaded to the gallery from Nev and Andy:

Here is my album on load testing:

I spoke to a few pilots with Monowheels and 914/Airmaster flying well over 1500
Lbs, even at aft CG stated in the manual for 1370 and they said the plane flies
OK, but doggier acceleration and climb but still acceptable. Andy and Nev said
the undercarriage of the monowheel is the weak link (and of course you are
eating into your reserve airframe strength). If your plan is to take off @ 1550
and burn fuel before landing, if you have a power failure after take off, good
luck. One thing keep in mind as far as maneuvering speed goes, a higher weight
increases the maneuvering speed (as far as the wings go anyway). 
Andy spoke of moving the CG ~ 1" forward of aft and ~ 1" aft of forward (I am 
going
by memory, please read document closely to verify) if flying at 1450 AUW.
I spoke to someone who spoke to the test pilot when test flying was being 
conducted
of the Europa and flying with a more aft CG at 1370 AUW was very recoverable
---From a multi turn spin, but it spun up like a maple leaf and it was deemed
a bad idea to allow a pilot with average skills to ever experience a spin of
that nature and have the ability and skills for an effortlessly recovery. 
If you ever have an official flight test routine performed on a Europa, I for 
one
would be very interested in seeing how a XS recovers from a multi turn spin
recovery at 1450 with an aft CG as stated for 1370 lbs.
The same goes for the glider wing. From what I understand Europa has a video of
glider wing test flying and spin recovery. Several times my request for a copy
was never complied with. Perhaps you may get better results and post on the
Europa club website?
I spoke with someone that said they talked with a pilot flying at either 1450 or
higher AUW on a trigear XS with quite a bit aft of allowable 1370 CG and it
was quickly discovered when landing that quite a bit of forward pressure was 
needed
on the stick at the flare, hence he would never fly in such a configuration
again. 
I will just mention that for Glider wings, without modification to spar (but 
only
after inspection as per SB) you can only fly slow and light. To fly faster
and heavier, a spar mod and front lift pin socket mod must be performed. Info
can be found on Europa's website, or I posted at the bottom of my Glider 
Information
Gallery, SB 17, SB 18 and MOD 78. The lower ones are the latest and greatest
as per today:
