Some pictures of the airplane and assembly. Here is the installation of the MK bellcrank, I used this method because the rudder post is already installed and painted, very easy to do with masking tape. Note that after the bases with bearings are installed I just used a Allen ball driver to catch the bellcrank, then using the same slided in the outer horns. Also shown the holes made for the wing attachment, the installed dowel under the covering is easily visible, just drill the first hole for the 4-40 bolt then a little recess over the same bolt for the bolt head.
