<DIV>My problem is limited thrust. The pack gives me about 5 mins of flight all straight and level. Loops, stall turns etc are out of the question. My auw is probably closer to 8oz so I should not have expected much out of the 340 pack.</DIV> <DIV> </DIV> <DIV>Colin.<BR><BR><B><I>Tom Simes <nsrca@shinymetalass.com></I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">On Sun, 8 Jan 2006 15:38:48 -0500 (EST)<BR>colin chariandy <CCHARIANDY@YAHOO.CA>wrote:<BR><BR>> I finally got the F3A flying today ( no snow, no wind, no rain).

just not getting much duration out of the packs? <BR>I know when I started flying my foamie outdoors this winter, I was only<BR>getting 2 - 3 minutes out of a pack that would normally give me 10 - 12<BR>minutes indoors. The duration was so bad I initially thought I had put<BR>a partially discharged pack on the plane. A fellow club member<BR>suggested wrapping my batteries in one or two layers of the 1-2mm foam<BR>packing sheet to help retain a little heat and that brought my outdoor<BR>times back in line with what I was getting indoors. Just FYI, I'm using<BR>2C Kokam 340s Etec 450s on a EPP foamy (4.9 oz. AUP w/340s).<BR><BR>-- <BR>Tom<BR><BR>_____________________________________________________________________<BR><BR>| , | Tom Simes<BR>---------(@)--------- AMA 230068<BR>--|-- NSRCA 3830<BR>' nsrca@shinymetalass.com<BR>_______________________________________________<BR>NSRCA-discussion mailing
