The above parameter defaults to 490Hz for multicopters. However I have a Hobbywing 20A quad ESC (4 in 1) and on this page for it;
http://www.helipal.com/skywalker-quattro-20a-x-4-speed-controller.html
It says;
"- Refresh rate of the throttle signal : 50Hz to 432Hz (432Hz is fast respond for Multi-rotors)"
Would it be a good idea to reduce RC_SPEED to 432 at the highest? What would be the problem in setting it even lower than this?

I would assume that 50Hz to 432Hz is the usable range for that particular ESC. If that's the case then setting RC_SPEED to some value within that range like 400Hz is probably wise.
