servo buzzing on HRS receiver

[fidspeed]

hi guys
sorry if going over old ground ,recently upgraded receiver to a futaba HRS to match my 3PK transmitter . I noticed my KO digital FET servo "buzzes" a lot more than it did before on my recently removed KO 301 receiver .
Is this normal in HRS mode ?

thanks in anticipation

this is normal all digital servos do it and metal gears seem to make the buzzing worse dont worry all should be fine

Personally I would drop the radio down to standard response, this increased buzzing could be a sign that the servo is being overworked... I have seen a servo get roasting hot and fail after being used in HRS by mistake.

thanks for the heads up guys

will a futaba HRS receiver work in normal mode ??

I expect the servo that roasted was not digital. I cooked a servo like this also that was not digital.

I've been running digital now for maybe 8 months in HRS mode and the digital servo's i now run are as good as the day i put them in. If your servo is digital you should be fine to run in HRS mode.

You can run PDS KO servos in HRS more or PPM, but PS servos ONLY in PPM unless you want to cook it. I run both and to be honest can't notice the difference in running in HRS or PPM modes.
