I suppose I didn't understand your question. The easiest way is often mechanically (same as differential and expo).

Reversing


Radios typically came with four servos, one or two of which were set up for reverse rotation (they usually had a colored dot or some such marker).

We didn't get reversing at the transmitter until about 1980 (for me it was the Ace Silver Seven that gave me reversing, D/R and expo for the first time).

The usual convention for normal rotation was that right aileron stick gave counter-clockwise rotation on the servo (looked at from above). This corresponded to the required rotation for a strip aileron setup in a low wing model. Generally speaking, you could, as Andy says, do reverse movement on the other controls mechanically (just by moving the push rod to the other side). But aileron was a bit inflexible, so that's where you started figuring out the installation.

It was quite an effort to get everything just right in terms of direction and throws.

By the way, there was no subtrim of course, but servos could generally be centered with a small screwdriver or Allen wrench down a hole in the output shaft. The output arms usually fitted onto a square shaft as there was no need for a splined setup, given the adjustability of neutral.

It's a good thing "they don't make them like they used to" - some of those old radios were downright AWFUL!
