Clive,
We made a strong steel support for the wings to avoid any damage to the
fuselage. I published a short report about our load test with some pictures
in the Europa Flyer #30, that you can find on the Europa Club website.
The load test is worth wile, but it is thrilling! Good luck

Bruno,
Thanks for your post -we can trust a German to provide some excellent
detail! That photo gives me great confidence in the design - they are bags
of cement?

Yes, these are bags of cement, borrowed from a local DIY shop.

Hi Paul,
Here are some pictures.
02+04 is preparation with a soft foam blanket on which we also marked the position of the concrete bags, each 25 kg. 07 shows the support winches, which you can release very slowly and jumpless
15 shows the measurement after each load increase, 16+17 the full load of each side and 21 the full load spread.
Each side 1035 kg concrete bags, therefore 2.070 kg in total. To this you have to add the wing weight of 94-100 kg complete, depends on build.
The winches were released free (you can see it on the loose foam supports). One problem was that the support timber sticks were too short, so that we had to do some work on the wing surface later.
A similar test was also done with the tail plane 100 to 150 kg and opposite (pictures 9839, 9842 and 9845
With picture 9854 you can see, that this load test on a classic one failed. The fuselage/cockpit was not correct made and the fuse started to bulk out. This was later repaired and than ok.
This is the wing load test, approved by the OUV and LBA here in Germany

Does anyone have any photos that show the entire wing under load where I can see the deflection?
