Hi all,

I'm trying to find more data about the R/C throttle control.

as I am to understand, the control input to an
ElectronicSpeedController (ESC) is over a repetitive 20mS frame.  and
in that frame there is a range between 0.5 and 2.0mS that is the value.  

That would make it so 0.5mS is a zero speed and 2.0mS would be 100% speed.

am I correct on this?
does anyone have a schematic for an ESC for a burshless motor ?

I'm looking for a 25,000 RPM motor to use on a PCB drilling machine
and these seem small enough and high speed enough to do the job. 
Unfortunatly, the combination of motor and ESC can run upwards of $1750 !

Any comments or suggestion are welcome.
