I don't know if it has ever been discussed but I've noticed a great deal of difference in the flying qualities of the airplane in regards to the position of the flapperons.

I have then on a rotary switch due to the minute differences it takes to make a big change.

It seems to me that the use of them will make a tail heavy aircraft fly well and the position creates all kinds of variables as to what the airplane will do.

I've only found this out on a Pizzaz and a Morris Su-Do-Khoi, I don't know if it will transfer to all types.

What kind of experiences can you share in this regard?
