Carbon Cub has carbon fiber rods wth a bellcrank midway up the strut I am told because the rod flexed to much when in one piece. Husky has pushrod elevator controls.

Bearhawk has push rod and rod bearing elevator controls, super smooth. Cable control up the strut to the wing bellcrank, push rod from there.

Which Wag model did that? You wouldn't happen to have any drawings (or pics) of this setup? Sounds really interesting!!

Drawings? You don’t need no stinking drawings! Just kidding, but it sounded right. I have no such thing. Third owner looking for the fourth owner. No original build pics, drawings, or likewise. It’s a “Acro-Trainer”.
The fellow that did it I believe did so incorporate easily removable or foldable wings. I’ve removed them but I have understood the folding aspect. Largely because I think foldable wings are a stupid idea.
I’ll look and see if I have photos of the connection points.

Okay found pics from a little while back. Don’t mind all the crap hanging off the window and the old shoulder harness.
Red is aileron, blue is flaps.
Aileron tube is in front, and has two quick disconnect pins to the push-pull tubes in the wings. Those obviously go to a bellcrank to the control surfaces.
Cables run from the attach point to the side, aft on an angle to a rear mounted pulley about mid height fuselage, to then angle frontward down to a bottom mounted pulley, so it can run forward up to one last pulley under the pilots floor outboard before attaching to the stick.
The flaps are electric. Plenty of naysayers but they are simple and work great. Actuator is internally mounted in the right wing, with a carry-through tube running through the cabin just aft of the aileron tube to attach to the left side. Again with a removable center section for wing detachment.
Flap control is a smart 3 button unit that allows 3 preset positions (up, mid, down) of your choice, or by using two buttons at a time you can infinitely move it to any position in the range of travel.

I appreciate you posting these pictures. I fly the Cubby (Sport Trainer) and have never seen anything other than pulley'd cables in any other build. These are great!

No problem- in contrast to a cubby this is like a supercub with front V brace and overhead X brace.

I was initially confused by the photo, then realized the upper deck is very Super Cub like...At least Wag copies good designs!

Doesn’t the Fairchild 24 have all pushrods except the rudder?
