The wing assembly starts out like many by hinging the ailerons with the supplied CA hinges. A string is built in place to assist in pulling the aileron servo wire (with 12" extension) through to the center.

Once the wire has been routed, the aileron servo can be secured in its mount.

Now the control horn is added to the aileron and the pushrod is sized and attached with a metal clevis at the aileron and an "L" bend and keeper at the servo.

At first the gear wires seemed a bit thin to me for a plane of this size and I was a little concerned, but the wire is good and strong and proved to be more than adequate.

The wires are inserted into the gear blocks in the wing and secured with metal gear straps.

If you've never made a pushrod before, it's about time you did. And Goldberg's method of using shrink tubing is much easier than doing it the old way (Thread and glue).

You'll need to bend the last ¼" of the wire and insert it into the pre-drilled hole with some medium CA or epoxy. Then just slip the shrink tubing over it and heat.

Now slide the pushrods through the fuse and out the rear exits. I found it helpful to make a sort of ramp with a small screwdriver to coax the wires out.

Note: Later, once the pushrods were attached to the servos and control surfaces, I noticed the dowel on the elevator pushrod was getting hung up on a fuselage bulkhead. I solved this by tapering the end of the dowel and had no further problems with it.

The two wing halves slide onto an aluminum tube. There are two dowels in the front of the wing, which plug into the fuse former, and then two steel bolts secure the wing at the trailing edge.

The tail section is like most, but rather than having to measure everything, the fin automatically aligns the stab. So you just put the stab and fin in place, mark the stab for covering removal, remove the covering from the stab bottom, and epoxy everything in place.

This was very easy and everything lined up perfectly.

Now the elevators and rudder are hinged and once the control horns are attached, the pushrods get connected.

The nose wheel strut gets a collar on the bottom to hold it in place and then the wire slides into the pre-installed mount.

One thing worth noting here is that the manual says that there is a flat spot on the wire for the tiller arm set screw, but there was no flat spot, so I ground one myself.

I had to chuckle at how well Goldberg stuck to the original design, even incorporating a "Breakaway Plate" style engine mount which is something I haven't seen since the 70's. But then I thought, "Why not?" It's a great system that can protect the plane from serious damage in case of a mishap, and if broken, it's easily replaced.

Now the throttle pushrod hole is drilled, the mount is screwed into place, and a small relief needs to be cut into one cheek for the needle valve.
