Default RE: Siai Marchetti SF260 ARF

Okay, both ailerons hinges have been fitted. Although I had to fill in one side and re-drill, because I was stupid.

Okay, So I need your guys help. I'm doing the slotted flaps and it's always a bit of a conundrum of where the hinge line should be. So, I did the tracing method that I saw here on RCU, but I added a 1/8" inch grid underneath the flap, to try and get a more precise location for the flap hinge placement. The idea here, is to get a gap at the top of the flap, that will be smaller, than the gap at the bottom of the flap when it is extended. The idea being that air will be compressed/channeled over the top of the flap, moving faster, aiding in lift.

So, does my theory and methods hold water? Comments welcomed!!!!!!!!!!!!!!
