I'm about halfway finished attaching the capstrips to the ailerons. The next step will be to sand them down and attach the aileron control horns. Looking ahead, the plans and instruction manual are very confusing about this step. It looks like the control horn is mounted inside the aileron. This looks a bit complicated to me. It will require me cutting the bottom sheeting which the instructions told me to glue in place before attaching the aileron. Can any of you give me some advice?

Sketchin, how's is the engine mounting going?
