Each of us has encountered a solution to a problem when building a model. I want to share my best practices. To build a curved pattern (for example: wing profile) I cut out a strip of foam and press it to the surface with needles (the assembled wing always has a different curvature than according to the drawing). Next, using a glue gun and foam pieces, I assemble the rigid structure of the pattern. Everything is visible in the photo.

Great idea.

YouTube is blocked in Russia. It would be great if someone would make a video clip with a step-by-step setup of the basic Flite Test models and the first throws on the grass for planning and the first flight. The main mistake of a novice modeler is that after assembling a model, he rushes to launch it into the sky. I use my practical experience when creating a model based on the author's drawing to 80%, making the nodes of the model different. For example: in the Julius Perdana models, I always increase the size of the ailerons by 2 times: the first model could not make barrels due to the small area of the ailerons.

Manufacture of long rods for steering surfaces .
To make long control rods, I use welding wire with a diameter of 0.9-1.0 mm. 1.I drill a hole in 20 mm thick hard plywood with a 1.0 mm diameter drill. 2. Insert the wire into the hole 3. Clamp the end of the wire into the drill chuck 4. Turn on the drill at maximum speed and pull the wire at a 45 degree angle. The result should be a perfectly straight line. twisted wire. I place the finished control rods in fishing rods glued into the fuselage of the model. I place the control servers in the nose of the model.

I continue to share my experience .When it is not possible to make a complex shape out of a bottle,
I make several pieces and glue them together into a whole. The photo shows a MIG-3 flashlight.

Not sure of the twisted wire advantage, unless there are problems you have getting small diameter high carbon steel wire that is heat treated to be harder. On the other hand, your process does work harden wire and pre stresses it, but would not work sucessfully for us. The 45/degree bend and twist process would break our wire which is about 1.5 mm for pushrods.

Not familiar with welding wire. The process mentioned above works with piano wire. I recommend wearing eye protection, long sleeves and leather gloves. I watched a youtube video from somebody that needed strait piano wire. I like using coffee stir straws to help guide the wire.

After stretching, the wire becomes almost straight. I also used cocktail straws as bowdens.But at the moment, I used the tips of the rods, which, passing through the entire fuselage, give additional strength.This allows you to make the fuselage structure lighter.
