Electric Weight: with or without batteries at US Nationals

Sat Jun 11 09:14:28 AKDT 2005

Mike,

What kind of flight times are you getting?  We're at 7.5 -8 minutes with the
3200s which is real iffy toward the end(particularly if the CD says to
orbit).  The prototype balancing charger that is due shortly supposedly will
give us another 10% which for us weight challanged guys(more ways than one)
will make these a little more solid for contests and making weight.  Are you
running brake on or off?

Thanks,

Richard
