C17 Globemaster III build - controls

Some odds and sods from the C17 build this week.  I had the entire fuselage assembly up on the ironing board again to check alignment and gaps, as I had the filler out I knew some bits needed attention :

An elevator pushrod installed.  These are pieced together from M3 studding, M3 ball links, and an M3 quick link.  The ball sits in my tufnol sheet horns, secured (or at least will be when she's done) with an M3 socket head cap screw and lock nut :

Here is the top rudder servo, in place with its link.  I have passed the link through the stern-post and onto an aileron torque rod horn that was let into the rudder and secured with epoxy and plastic tube.  This keeps the rudders completely horn-free externally, and the servo will be covered with a flat plate for access :

M3 pushrod hardware on ailerons next.  These were from RCWorld, listed as an M3 carbon pushrod kit.  I'll be getting those again, they're great!

So, that's all the control linkages done, apart from the starboard flap.  The starboard wing is moving along quickly, and all I have left to do is the flap canoes.  The rear fuselage has now had its 3rd (yes, 3rd..) skim of filler and sanding back, and at this point I think is ready for the brown paper.

Items ready to glass are :
Front fuselage
Port wing
...and as mentioned nearly the rear fus / fin assembly.  I will have to get a move on with printing the engines!
