I spent the first hour reviewing Section 7 (building the wings) to Sec 7-9 to verify that the quick build steps had been accomplished. The next step is to install the aileron brackets to the rear wing spar, but first I need to prepare the parts from the aileron mount sub-kit. First I deburred the edges of the 8 aileron plates W-413 and W-414. Next I deburred the 6 AA6-125x3/4x3/4 precut angles.
