By hooking up this tester to <BR>> all three leads of the motor, you can test the motor for proper <BR>> functioning.<BR>> <BR>> This has become an issue when several pilots had speed controllers <BR>> burn up when the battery was hooked up to or disconnected from the <BR>> speed controller. When the flaw is present and the motor is put in <BR>> one or more "sensitive" orientations, the speed controller burns up. <BR>> This happened to one of the Norwegian competitors on the first day of <BR>> the Prelims and we watched helplessly as the nose of his airplane <BR>> caught fire.<BR>> <BR>> Strangely, if the motor isn't stopped in one of these "sensitive" <BR>> orientations, it appears to function normally. An unnamed pilot, who <BR>> rode to the F3A WC/Nats with me, burned up three speed controllers in <BR>> the last few weeks before the Nats, before replacing the motor in his <BR>> Black Magic with another motor from the same manufacturer.<BR>> <BR>> Can anyone identify the source of a brushless motor tester which is <BR>> available for our brushless motors?<BR>> <BR>> Ron Van Putte<BR>> _______________________________________________<BR>> NSRCA-discussion mailing list<BR>> NSRCA-discussion@lists.nsrca.org<BR>> http://lists.nsrca.org/mailman/listinfo/nsrca-discussion<BR></DIV> </div></body>
