There is a setting for current slope or ramp. If you have it too sensitive the controller could shot down when you power up the plane in long vertical maneuvers. I didn't follow all the e-mails but this happen to me one time with a CC controller. <span><br><br>Vicente "Vince" Bortone<br></span><br>----- Original Message -----<br>From: "colin chariandy" <cchariandy@yahoo.ca><br>To: "General pattern discussion" <nsrca-discussion@lists.nsrca.org><br>Sent: Thursday, June 9, 2011 9:41:55 AM<br>Subject: Re: [NSRCA-discussion] E-deadstick, trouble-shooting.<br><br><style><!-- DIV {margin:0px;} --></style><div style="font-family:arial, helvetica, sans-serif;font-size:12pt"><div>The losses(heat) is not only dependent on current (I2R) but also Mosfet switching losses.
