Low timing, medium throttle response, medium start power. In general use the lowest start power that consistently starts the motor. If the motor oscillates at startup, increase the start power.

In auto calibrate mode, the low and high values are set at default values….there is no guessing of any kind. To recall, the defaults are 1.35ms for “low” and 1.7ms for “high”. The ESC will not arm until it sees a value less than 1.35ms, and if it sees a value less than 1.35ms, it resets the “low” to match the lower value. Most radios with default endpoint/ATV values are in the range of 1.2ms low and 1.8ms high. After the ESC is armed, it “sees” the throttle range from the lowest value (likely 1.2ms) to the default high of 1.7ms. Going to full throttle after the ESC arms will allow the ESC to reset the high value to something greater than 1.7ms.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Castle and many other ESC brands have default settings that allow the broadest range of users to use the ESC without having to do any programming. Having spent a fair bit of time with Patrick del Castillo and a number of the Castle engineers, they would be quite amused to hear Castle is designed for the sport fliers. Patrick has always had the goal of making ESCs that would provide the best performance with the best motors….he despises any change in code to accommodate “sport” motors if there is a chance of losing any performance on the best motors.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><br>Dave<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> NSRCA-discussion [<a href="mailto:nsrca-discussion-bounces@lists.nsrca.org">mailto:nsrca-discussion-bounces@lists.nsrca.org</a>] <b>On Behalf Of </b>Peter Vogel via NSRCA-discussion<br><b>Sent:</b> Wednesday, July 30, 2014 4:11 PM<br><b>To:</b> Scott McHarg; General pattern discussion<br><b>Subject:</b> Re: [NSRCA-discussion] ESC Motor Combo<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Sounds like a Castle ESC in "Auto" endpoint mode.

Essentially, if you start at idle and bring the throttle up slowly as if you were in the air flying transitioning from a down line to horizontal, the RPMs only increase slightly even to full throttle. Two takeoffs were aborted due to this. If you jam the throttle from idle to full throttle, the motor comes alive and performance is spectacular and it will act fine with smooth transitions for a period of time if not the rest of the flight.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:blue'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:blue'>Just mainly making sure there are no specific hangups with this combo that y'all can think of.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:blue'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:blue'>Thanks,<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:blue'>Scott<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:blue'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:blue'><o:p> </o:p></span></p></div><div><div><p class=MsoNormal><b><span style='font-size:13.5pt;font-family:"Comic Sans MS";color:#3333FF'>Scott A.
