So if we are to get better battery solutions in the future it will probably come from a different technology than the current lithium offerings.

While the motor is an effective generator with the controls available, the issue is the ability of the batteries to accept the resulting high charge rate. Some systems have been
designed using capacitors to smooth the flow, but large capacity requirements limits practicality. Of course with LiPo charge rates in the 1 - 3C range, this becomes even more problematic for our systems.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Earl</FONT></DIV> <BLOCKQUOTE style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A title=bob@toprudder.com href="mailto:bob@toprudder.com">Bob Richards</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=patternrules@earthlink.net href="mailto:patternrules@earthlink.net">patternrules@earthlink.net</A> ; <A title=nsrca-discussion@lists.nsrca.org href="mailto:nsrca-discussion@lists.nsrca.org">NSRCA Mailing List</A> </DIV> <DIV style="FONT: 10pt

You mentioned the brake eating gears. I'm sure you meant the conventional brake that flat out stops the prop. What's your thought on the Hacker f3a brake that comes with the competition version of the speed control? We haven't seen or heard much of anything about this motor or the controller since the Worlds.</FONT></DIV> <DIV><FONT
