Has anyone changed the max angle on the firefly flaperons? What was the result?

I have Firefly sn- 22 Just curious why you want to change the angle.

I was reading a book on aircraft design and was curious if anyone had increased the angle of the flaperons. With the monospar on the firefly I was wondering if there were problems with torsional rigidity. When I put mine together I was expecting more angle, but I'm used to 150's, 172's, etc.

Do you need to improve the roll function or the flap function? I have given alot of thought to improving roll but I would not want to increase drag. I think a firefly with 1% more drag could be renamed cinder block. Of course improving roll will create some added drag , my thought was to leave deflection as is and add an inch or two to the flaperon cord. But this might induce flutter. Far to many projects to try it now , at some point in the future I hope to build new flaperons and give it a try.
