ALignment of the Flapperons took a bit of time and required more then one hand. I used a 20 mm spacing from the trailing edge of the wing to the leading top edge of the flapperon while in a semi neautral position. you can double check by rotating the flapperon and the 20mm gap does not change through rotation.

Here is a pictrue of the slats attached, the bent edge makes for a very clean line.

The wing root on the STOL 750 took a quarter the time it does on any other model. this was acheived by aligning the trailing edge and using the pre-drilled holes to align up the rest of the root. There was no trimming involved it was all set from the Factory.

Below are a few more pictures of the flapperons.
