I built a dozen CG Cub kits back in the 90s for glow power, this is how I covered them all.

Always cover the bottom surfaces first, that way you can wrap the top around to the bottom and see no lines from above. So cover the bottom of the Wing first, then the top and wrap the covering around to the bottom. Same thing on the elevator / horizontal stabilizer too.

On the fuselage, again cover the bottom first. Cover the front of the fuselage on the top in front of the windscreen with a piece that is trimmed to the sides if you are making it the same color as the rest of the fuselage. I cover the sides and have extra material to cover the turtle deck to the center. The turtle deck is hard to do without showing lines, cover one side first then do the other side and get some really sharp scissors to cut the line as straight with that center rod that runs down the middle to the vertical stabilizer.

For tools, have the sharpest scissors with clean blades to cut off the extra and make the edges neat. Get everything on good with an iron first, always work the air bubbles out as you go when covering solid flat surfaces. Us the hot air gun to get rid of wrinkles and tighten everything up. Make sure you have dry installed all your hinges and control horns before covering them, it is easier to cut the spots open after you have covered the parts then trying to cut slots and holes after it is covered.

Your fuselage looks good, but I would do a lot more sanding and use the light weight Spackle for walls and ceiling to fill in holes and smooth out all the glue areas. If it is rough to your touch it will show through the covering big time. Surface prep is critical in having a good finish, sand it all smooth with finner and finner sand paper till it is butter smooth.

The real ones have a cable that connect the top aileron control horn to each other,

The lower control horn is connected by a cable that runs down the wing strut, into the cabin, to the bottom of the stick. The control stick pulls the ailerons down.

In static on the ground the ailerons droop an inch or two. In flight the lift from the airspeed pulls then to trim.

That little bit of slack allows you to attach or detach the aileron cables for wing removal.

I'm picturing a servo under the pilot with a forked control horn for each aileron and a control stick in the center of the fork. This would give the pilot a simulated stick movement like the real deal.

Thoughts on this?
This is a nice model as designed. You will be better served if hold of on extensive modifications, until you get a Cub with more accurate scale outlines.

Looks great Conn! There is nothing more memorable than that first build. When it's in the air the first time it will make you smile. Knowing how it's built gives confidence added w the reward.

Tom is right about the scale outline. The Goldberg Cub flies really well, but the outline is not real scale. First thing you notice is the strip ailerons instead of the barn door like on the full scale plane.
I stuck with the strip ailerons because I planned to fly the Cub with floats. The strip ailerons put the aileron servo(s) inside the fuselage and away from water spray.

I mentioned before, the Greatplanes 40 size is the same cowl with both
sides of the engine.

I was extremely disappointed in the GP40 cowl. Fiberglass Specialties supplied a very nice one (which I modified for battery access).

The Fiberglass Specialties Super Cub cowl for the 1/6 Sig Cub can be made to fit the Goldberg version.

That is a very clean battery hatch approach.

The 25E GEAR ARRIVED !!!!! :-). Thanks for tip on that!!! Very nice. Actually I like it better than the Robart at 3 x the price.

Now for color decisions and cowl. If I go bush plane route. The eflight carbon z cub wings have turbulator strips that are added just ahead of the spar. Doesn't look like the are sold separately. Maybe a call to HH is in order.

There's just something about the traditional yellow cub though we all love
