When you decrease your servo speed, be sure to decrease your servo torque too, or you will still be "modern."

And while you're at it, don't use a PPM radio - after all, Kaz didn't.

And be sure you use paper instead of electrons to send your messages. After all, Algore hadn't invented the Internet yet. And no fuel injected automobile to get to the flying field, either!

As you can see, change is not necessarily bad. Construction techniques change as people find better ways to implement them. You can have a computer radio and still have limited performance by leaving it in the default settings. You can decrease servo speed with a computer radio, but you can't reduce torque that way.

"Modern" isn't construction techniques or installed electronics. Modern is aerodynamics and power:weight, handling and performance.
