Today I did the cutting a drilling of the rudder and vertical stabilizer tips, just like I have done previously for the elevators and horizontal stabilizer. I'd say that these were just the slightest bit tougher than the horizontal parts. Still not too tough though. They will definitely require some filling and shaping to get them to fit perfectly though. The VS tip sits higher than the lip on the bottom edge would suggets, so that it lines up nicely with the rudder. And in the middle of the rudder, the lip is a bit high, too. The end of the rudder tip also doesn't quite make it to the back edge and is just slightly thicker than the rudder where it ends. So lots of little bits to perfect here.
I also finished up the drilling of the right HS tips too.
