I aligned and drilled the holes for the flap crank and torque tubes. For the flap crank holes I drilled to 1/8, then #13, then reamed to 3/16″.
For the flap horn holes I drilled to 1/8, then #13, then 15/64, then reamed to 0.247. I didn’t have a W-730 bellcrank jig in my kit (I expect it comes with the wings) so I 3d printed a jig with the appropriate dimensions.
I then shaped the flap torque tube bushings per the plans. I used a 3d printed template here too which made it quick and easy.
