<DIV><FONT face=Arial size=2>Gray, hope you can find all the parts, especially
if Ike is also coming along behind Gustav. Sounds like a flight pack
problem--bad cell.</FONT></DIV>
<DIV><FONT face=Arial size=2>I just purchased several NiMH (1200mah)
batteries to replace old stuff as am getting back to flying. My past experience
with them is they need 3 or more cycles of slow charge to come up to capacity.
Here's what I found:</FONT></DIV>
<DIV><FONT face=Arial size=2>#1set-slow charge-Airtronics Rx. charger-(36
hours)667mah, again 721mah, again 750mah, again 850mah, I have since put 6
cycles using a Sirius charger and now am at 906mah.</FONT></DIV>
<DIV><FONT face=Arial size=2>#2-same approach 969mah, again 975 mah, again
1030mah, again 1085mah. after four cycles on the Sirius charger it is
1115mah.</FONT></DIV>
<DIV><FONT face=Arial size=2>#3 same approach 1064mah,again
1167mah,again1235mah. Then three cycles with the Sirius charger and holding from
1215mah to 1238mah.</FONT></DIV>
<DIV><FONT face=Arial size=2>I stll have 2 to go.</FONT></DIV>
<DIV><FONT face=Arial size=2>I am discharging using a Sirius discharger-set to 4
cells, and discharge at 250ma. I tried set1 at 500ma rate and got a drop back to
724 (@ 200 mah). I found little difference between the 125ma and the 250ma
rate.</FONT></DIV>
<DIV><FONT face=Arial size=2>This is also consistent with past experience (6
years ago) with 4 sets (different mfg.)where I never got 1 out of
the 4 over 3/4 capacity.</FONT></DIV>
<DIV><FONT face=Arial size=2>Makes me think seriously about going back to nicads
where weight doesn't matter.</FONT></DIV>
<DIV><FONT face=Arial size=2>By the way these are not el-cheapo brand
cells.</FONT></DIV>

face=sans-serif size=2>Yesterday on my 4th flight of the day my PCM Stylus
went nuts. PCM program was set for idle throttle and about 5-6 clicks(trim
wise) of up elevator-all other surfaces neutral, and this was tested as such
by turning off the transmitter. As I passed by center I noticed that I
could not gain altitude and the the throttle started going from idle to
high...then ailerons started oscillating small left-right deflections. I cut
the throttle to the kill position but the engine persisted up-down bursts. I
was able to do a 180 degree turn with aileron coming back to center...never
losing altitude, but unable to change the altitude,elevator seemed
unresponsive. As I passed by center again I was losing more and more control.
The plane flew over the wooded area south of the field at about 200 feet high,
I could not turn and the ailerons rolled the plane upside down and it went
straight down into the trees. This whole episode last about 45 seconds. Cannot
find the plane, and remnants of Gustav are headed my way.</FONT>

receiver to do such a thing?</B> If I had and intermittent signal, once the
receiver did get a signal the only two throttle signals should have been idle
(PCM hold) and off (transmitter). I am going to send the transmitter in
just to get checked.</FONT> <BR><BR><FONT face=sans-serif size=2>Thanks
