Redesign and reconstruction of the world... according to Cees
RCU members and guests are quite fortunate to have access to modeling tips, design ideas, discussion of aerodynamics, the use of various materials, the complex physics behind ''flight'', chemistry, artistic design, the proper use of footnotes and the finest contributors provide insight and explore the most subtle strategies/techniques to radio controlled flight...for this I am both humbled by their greatness and marvel at their ability to chose language with such precision and clarity.
RCU might consider helping the less experienced RCU participant a quick and easy method to identify such modeling genius...maybe an exclusive ''avatar'' to those RCU ''Real Men of Genius'' type contributors. Maybe some kind of voting could be arranged to chose from examples below?

Gents,
After this post I think I have to show you Rusty is true with an example.
I read in aerodynamics:
Anti Yaw Device

When you want to fly with Horten planes, see picture 1, (Northrop Wings for the USA) then you need a computerized transmitter to control the direction of the plane.
I did build a calculator in my transmitter to calculate the feed forward control of the drag rudders with analog electronic, operational amplifiers.
To make the multiplier functions, I use light dependent resistors (LDRs) in the feedback of some operational amplifiers, eight total. The elevator channel controls these LEDs that shine there light on the LDR’s. The signal of these amplifiers is used to control the drag rudders of the plane. The input signal of these amplifiers are the channels of the ailerons. Some diodes, resistors etc. to adjust the relationship like expo, also in inverted flight because of the use of the bi-convex airfoils.
This devise was special designed to fly with the Horten plane.
Now I also use this after recalibration to fly the Taurus, so a selectable part of the rudder deflection is calculated from the input of ailerons and the elevator. Of course I can still control that rudder for the second part of deflection. During flight I switch over in two levels or off.
With this device the differential of the ailerons is overruled, so I do not use that.
The profit is, during inverted flight it is still functional in the right direction.
I think this is an example of what Berusty did want to tell, because let us be honest, who does still fly a classic pattern plane with electrical lights “in” his transmitter as with the old radio tubes in the past? Taurus Flyer.
The electronics I have to make black again (see the orange circle), because, also my GRID LEAKS, it only can be light from outside in and then my plane will make an uncontrolled spin.

Glue on the components,to keep them on the right place (LOL)
