Hi again Ian,
Well, I ordered a couple of S9257 servo clones, which are meant for 4.8V only systems. Else they burn out fast.
My UBEC outputs 5.3V if I remember right, maybe 5.2V
So I do not want to get my $14 servo exploded
Well, it`s not that much but still I`d like to have it running for long time instead of some flights.
Except of a crash caused through a locked servo (not that I do not crash anyway)
Some say they don`t have a problem with the S9257 and its clones even at 5.5V. Some had it burnt down at the second flight.
I don`t want to risk.
Now Align had made such a voltage step-down as they had made an esc that output 6V (or something, I can`t recall) which was not suitable for the Rx or servo (can`t recall).
It uses two HER503 Fast switching diodes. Parallel into different directions.
Now I wanted just some voltage drop, only 0.4V or something close so to get my 5.2-3 to 4.8V the servo must run.
If the Scottky are fast enough not to confuse the signal line, as the gyro will be powered through this module too, then all must be OK.
The servo must be powered @4.8V but the signal line must use 4.8V pulses too, as some say. Of course I don`t know if the gyro will still output (to servo) the same voltage of its input (from Rx) to the signal line or the one it is powered.
So... I ordered them and see how it goes I guess.
