I don't understand how changing from 20C to 40C<br>pack makes a difference using the same Motor and ESC combo. If it's<br>battery heat, my electronics background would tell me the pack is<br>probably being dicharged too deep. Not good for the life of a battery.<br><br>I suspect the result of not changing the Motor/ESC and only changing<br>the battery will reult in a shorter battery life; and, over loading<br>the power plant which will probably result in damaging the ESC and/or<br>the Motor.<br><br>I could be wrong, cause I really have no experience with electric<br>power set ups in planes. I just don't understand the logic going from<br>20C to 40C and the result being "too hot for intermediate".<br><br>It wouldn't surprise me to see Masters or FAI having a higher power<br>set up, like 3,500 to 4,000+ watts. Then depending on the max current<br>draw, 40C may make sense.<br><br>My set up will be about 2,700 to 3,000 watts based on specs... It may<br>not be sufficient for Masters or FAI.<br><br>Perhaps this will turn out to be a good constructive discussion for a<br>number of people like me, but I'm curious as to other opinions who<br>have practicle knowledge.<br><br>Larry Diamond<o:p></o:p></p><p class=MsoNormal>_______________________________________________<br>NSRCA-discussion mailing list<br><a href="mailto:NSRCA-discussion@lists.nsrca.org" target="_blank">NSRCA-discussion@lists.nsrca.org</a><br><a href="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion" target="_blank">http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</a> <br>_______________________________________________<br>NSRCA-discussion mailing list<br><a href="mailto:NSRCA-discussion@lists.nsrca.org" target="_blank">NSRCA-discussion@lists.nsrca.org</a><br><a href="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion" target="_blank">http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</a><o:p></o:p></p></div></div></div><p class=MsoNormal><o:p> </o:p></p></div></body></html>
