This one page in the manual, the rudder pedals, ends up taking a long time because of so much drilling and riveting. Really begins looking like a plane after you're finished, though. They don't mention in the manual, but don't rivet too close to that pedal hole on the front side, because the next step on the next page, you have to pry that up a bit to install a piece of hardware. I'll have to remove that rivet temporarily on mine.
