Anthony.<br>Your question is exactly why I started the web site. There is no single <br>place to find the large amount of data that exists on battery and motor <br>longevity and performance. Everyone has their personal data and <br>experiences but unless you contact everyone flying electrics, you won't <br>be able to get a large enough sample of data to draw valid conclusions. <br>As far as batteries, I think you will find answers all over the board. <br>I know of some who have only had good performance from a set of <br>batteries for 20-30 cycles and others who have 200+ cycles on the same <br>type of batteries. What I am trying to do is see if the 20-30 cycles is <br>the norm, or is the 200 correct, or is the average somewhere in the <br>middle. Only a large enough sample will tell, and hopefully that will <br>happen. I know that many/most/ of the really low cycle life packs were <br>caused by mfg defects and were subsequently replaced by the mfg. <br>As far as the Flight Power F3A packs, the consensus is that they are <br>really strong for maybe 50 flights, then degrade quickly and the average <br>cycle life is probably 100 or less. I consider a pack run out if it <br>can't provide adequate power for normal contest flight. Not completely <br>dead, just too weak for a contest flight. For example, my Flight Power <br>F3A pack has 110 cycles and I consider it too weak now for a contest <br>flight. On the other hand, I have 2 sets of TP 5300 ProLites with 150+ <br>cycles each and fly them regularly with good performance still.<br>Remember that the user has ultimate control over how well things work <br>over time. We can all list people who could never get glow motor XYZ to <br>run well while others have stellar performance over a long period of <br>time. Same for electrics. Everyone will agree that there is a definite <br>learning curve to electrics and the best way to ensure success at first <br>is to copy a setup and charging regimen that has been used by others <br>with success over time. <br><br>Chris<br><br><br>Anthony Abdullah wrote:<br>> I was looking at the site and noticed how quickly / few cycles it takes for lipo performance to start to degrade (20-30 cycles in some cases). Is the "premature" degradation on the site just a function of a small sample or does performance on average start to decrease in as few cycles?<br>><br>> What is the average number of cycles others are seeing with F3A lipo packs before they start to lose capacity? <br>><br>><br>> --- On Sun, 9/7/08, JEREMY CHINN <lagrue@hotmail.com> wrote:<br>><br>> <br>>> From: JEREMY CHINN <lagrue@hotmail.com><br>>> Subject: Re: [NSRCA-discussion] Electric pattern recommended equipment<br>>> To: "General pattern discussion" <nsrca-discussion@lists.nsrca.org><br>>> Date: Sunday, September 7, 2008, 6:55 PM<br>>> Chris Moon took the time to put up the new site <br>>> <br>>> http://www.electric-f3a.com/<br>>> <br>>> Lots of great information to be had there.> Date: Sun,<br>>> 7 Sep 2008 17:30:52 -0500> From:<br>>> glmiller3@suddenlink.net> To: aabdu@sbcglobal.net;<br>>> nsrca-discussion@lists.nsrca.org> Subject: Re:<br>>> [NSRCA-discussion] Electric pattern recommended<br>>> equipment>> Anthony,>> I've used the Axi<br>>> 5330 F3A and the Dualsky 11T with very good results from<br>>> both.
