Can he tell you that it looks like you're dropping a wing in the corners? What if he says you're drifting out to 200 meters, or that you just about missed the pole on the turnaround? All of these things are in-flight feedback, based on audible or visual feedback from the model, that you, the pilot may or may not have observed as keenly as your caller. And you, as the pilot, may or may not act on this feedback, which is different than an automated closed loop feedback system. It's called free will. If your caller grabs the sticks to fix any of these issues for you, it's another matter entirely.<br> <br>So now there can be telemetry feedback. It is only a closed loop feedback system if there is a mechanism in place to take specific action on that feedback in a pre-determined fashion, which results in having corrected some condition of flight with the model. How a low voltage warning could count as closed loop feedback is debatable, but I guess that if it's OK for a hearing imparied pilot to be assisted by a caller to land when there's an engine problem, then it ought to be OK for an audible beep or a glance at a telemetry display to clue you in on what's happening inside the model, before it becomes a safety problem.<br> <br>Just for perspective, your servos and voltage regulators are all closed loop feedback systems. So is the pressure regulator on a YS, if you are still running one. None of those closed loop systems fly the model for you. They only serve to stabilize that part of the system that you are in command of.<br> <br>Ed<br> </span><o:p></o:p></p><div style='margin-left:.5in'><div class=MsoNormal align=center style='text-align:center'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black'><hr size=2 width="100%" align=center></span></div></div><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt;margin-left:.5in'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black'>From: <a href="mailto:jnhiller@earthlink.net" target="_blank">jnhiller@earthlink.net</a><br>To: <a href="mailto:nsrca-discussion@lists.nsrca.org" target="_blank">nsrca-discussion@lists.nsrca.org</a><br>Date: Mon, 21 Nov 2011 09:12:15 -0800<br>Subject: Re: [NSRCA-discussion] No telemetry rule & new radio systems</span><o:p></o:p></p><p style='margin-left:.5in'><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:navy'>"Closed Loop" ??
