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;

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?

Thanks Crady that's what I thought. Can anyone elaborate on side effects of setting too high and too low?

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.
