<div>Okay I see what you are saying Dave. I think you are after a form of voltage regulation to power the plane as we do on airborne radio packs. To me, that's far simpler than I originally believed it to be. There is no magic done to regulate voltage down from a 2 cell lipo for example, to a usable magnitude in the airborne stuff. It sounds like it's a similar arrangement for the power plant also, but don't know enough about ESC's to make a reasonable assessment. In the case of the airborne regs, Ed explained his design. There is nothing there construing a violation.</div>
<div> </div>
<div>I am also using his IBEC design for powering the CDI unit on the SAP180 gassie and there is no violation there either. Just straight forward regulation from an RX port to the CDI and filters to eliminate spurious signals from the CDI/spark plug wire back to the RX</div>

<div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">The OS EFI looked at throttle position (taken from the throttle servo signal pulse width), RPM, and temperature. I disconnected the temp sensor and found it made ZERO difference in running characteristics under normal conditions. Others reported the engine would not even start without the temp sensor connected. My understanding is that EFI computer unit basically compared throttle position to RPM and adjusted the mixture to reduce rich/lean spots as the engine came on/off the pipe.</SPAN></FONT></div>

<div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">So far as the ESC feature I would like to have…..it is not a governor like the governor mode from the heli software or the governor mode Dean has worked with for CL Stunt. And I certainly don’t want my electric setup to emulate an IC (if I did, I’d just fly IC). What the feature is, is a way to “clip” peak power at the beginning of the discharge cycle to maintain a constant peak power (if/when requested by advancing the throttle stick to 100%) and constant part throttle power. In the instance of a fresh battery being capable of 6500 RPM, it might be limited to 6100 RPM…..and ½ throttle would be 4500 RPM (for instance). As the battery is discharged, it might only be capable of 6200 RPM, but full throttle would remain 6100 RPM, and ½ throttle would remain 4500 RPM. Think of it more as the way modern TX output strength is controlled……….whether the TX battery is freshly charged at 11 volts (Nixx) or near depleted at 9.3 volts…the signal output strength is the same.</SPAN></FONT></div>

<div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">So far as a 45 upline or vertical upline……certainly electric or IC both need throttle adjustments to maintain constant airspeed. A “governor” that maintains constant prop RPM could be applied to either setup (and potentially maintain constant airspeed without an input from the pilot). In practice, less throttle adjustment is needed with an electric, because as the load on the electric increases (airspeed decreases when climbing), the electric motor attempts to maintain the RPM from the start of the climb (KV*volts) by drawing more amps to maintain the RPM. IC doesn’t do this….more load on engine results in a loss of RPM (absent any specific tuning effects of the exhaust system, mixture, etc).</SPAN></FONT></div>

Dean used a good example: at near the end of the flight, let's assume there is a diagonal or vertical. The battery has lost some pop and the motor won't be able to keep up under constant throttle conditions. The pilot would need to make a throttle adjustment to maintain momentum. If the ESC had this new programming, the pilot would fly through this without hardly noticing or changing his flying, just like we do with ICs. I certainly am NOT opposed to reducing pilot work load...it's the how not the what. </SPAN></FONT></div>

<div class=MsoNormal><FONT face=Arial color=black size=2><SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial">I actually was only halfway joking I said "Ban the YS Pressure Regulator", or something like that. Not that I really think it should be banned, but for everyone who thinks it would be cheating to have an ESC that can auto-compensate for dwindling battery voltage, then you ought to seriously think about why it is OK to have a automatic pressure regulator in a recip. There isn't much difference, other than one is wet and the other is dry. And the other key point about having an ESC with this feature is that it doesn't do anything to alter the piloting of the model based on the external conditions that the model is encountering. All it is doing is de-rating the output of the the battery to make it consistent throughout its useful operation range. <br>
