There you see it. Pictures of well built wings and NO warp.

Success start in the brain.
I say that because the brain controls the steps taken toward success.

A reliable flat work table ___
Selection of straight materials ___
The glue of your choice.

You may not agree but gluing is an art and so is soldering.
It starts with theory which resides in the brain. That theory controls the steps taken in accomplishing any work process.

Some fellows do not believe in theories and it reflects in their achievements.

We read a lot about balancing our models longitudinally and laterally.
We read very little about a more important subject. That subject is geometrical accuracy of our builds.

Warps, non-symmetrical incidence, improper decalage, loose covering particularly on the wings changing the airfoil contour as the model is maneuvered, looseness of control surfaces (slop), all contribute to make a model more difficult to control (to fly).

I repeat what I wrote earlier. You are a better pilot than you may think if you fly a model that has good geometry. It is a lot easier to make it do what you wish compared to constantly have to feed radio commands because the model is unstable.

Fly the model ___do not let the model dictate your control inputs.

and have a great day at the flying field.

Come home with a big grin on your face and the results of a great flying day ___my wish for all of you.
