Ailerons have now been cut out having been built in with the main wing structure. There is a clear gap to cut to and it was a simple job. Then the open structure at cut edges is covered with 0.4 ply again straight forward. The aileron horns were cut per plan from hard 2mm fibre board and slotted neatly on the spar with epoxy.
PS: John; where do those melons and potatoes in the background go. Are you building a transport glider to drop food off for the shielded? 🙂
