Yeah and Hornet ailerons can be installed upside down on the wrong wings as
well. Its hard to do but not impossible. Not with quite the same consequences
but still serious. Crossed Blanik rudder cables can also put some excitement
into peoples lives too.
Be vigilant out there.

That would be correct,
They were fitted incorectly for transport post re-finishing the wings in
parts and then things were not picked up pre the test flight.

Thanks John
So I am assuming the problem only occurs due to incorrect assembly and not
during operation after a correct assembly.
