Jose, your theory on this subject is mostly correct however as we have stated before, it's just not applicable to this particular model.
Have you actually tried it with this particular plane?
I have and I saw NO wing drop what-so-ever even at high spoileron deflections.
It may be that the loading is so low the response normally seen with most gliders does not appear.
Deploy the spoilerons, the plane slows, looses lift and plunks down, which is what the OP has asked for in many threads.
