Mod servos without microcontroller

[Bubbles]

when modifying the servo the tutorial says to use a .hex file to center the servo, however i was wondering if i could just hook it up to a receiver and use the transmitter joysticks to center it instead.

thanks in advance

that'll work. just make sure the trim is set to zero also

I did that and I had to modify them again after I got my microcontroller working. I had the trim settings set to zero.

your servos were running at a different voltage in your circuit and off the reciever

[Trumpkin]

I use the same battery for the reciever and the microcontroller.

[airman00]

well either the pulse wasn't the same OR the servos were getting different voltages each time even though the batteries were the same

[Bubbles]

why would the amount of power they were getting affect whether or not they would go back to zero?

[airman00]

well the servo has circuitry inside it , so different power means the circuitry works slightly  differently
