Minor update - no pictures yet:

Went to the hobby store and got a new pushrod as well as some clevises. Per some of the recommendations here, I also picked up a piece of 3/8" sheet basla to cut to size and mount on the underside of the tail to serve as a drag plate

The wing servo is mounted and hooked to the ailerons. Elevator is hooked up, as is the rudder/front wheel. The foam-wrapped battery is still rather loose, so I need to rethink and repack the radio gear a bit and then put the receiver in. At that point, the only remaining thing to do is the fuel tank and then the wing decals.
