This system is smart that isolates the bad battery if something goes
wrong. In this way, the bad battery won't drain the good one.
The LED in the receiver tells you if the battery has been isolated. <o:p></o:p></span></font></p>

Since the plane is in good condition probably you can check. I think you

Gray, <br>

Yes, that is good news. Clearly the battery was the problem. I had
heard that some chargers get a "false peak" and stop charging when
the battery is not really fully charged. I wonder if this was the
problem. <br>

Lance and I went out and found the plane right where it was supposed to be. Do
not know how I missed it the first day, so I am going to say that someone went
into the woods Monday night and moved it .</span></font> <br>
<font size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'><br>
What is amazing in the minimal damage the plane has considering it went
straig ht in from 200 feet, albeit at a slow speed. The horrible reverbed
cracking sound Keith and I heard was the carbon fiber wing tube breaking. Both
wings have limited leading edge damage, the stab has a golfball size divot on
the R LE, an easy to repair crack in the fuse (buckle failure) behind one wing
and a little nose ring area damage. That is all.</span></font> <br>
<font size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'><br>
The battery pack had broken the 3/8 bals a stic ks on impact that were bonded
into place (my battery packs are not "removeable" per say) and the
battey pack was on the ground at the nose of the plane. The plane was standing
vertical on the undamage spinner being held up by the tree branches.
Once we got home we hooked eveything up and of course it all worked fine.
Knowing that the battery pack essentially had the same charge as when the plane
went in, Lance took the battery pack home for diagnostics. Using the
Robbe charger he cycled the1450 mah &nbs p;pack down....it read 80 mah. He
then charged it and it read 1000 mah. Anthony described a NiMH "brown
out" and that is starting to make alot of sense. 6 volt packNiMH ,
drained does not just die like a 4.8 volt NiCad. Also an important note is I
now think the plane was going in and out of PCM lock. When I tested PCM lock
the throttle did cut, but not to low idle. It cut to about 20% throttle (programming
error), hence the pulsing of the throttle that I exper ienced. If this
diagnosis is correct then it is a testament to using PCM as I was able to fly
the plane for 45 seconds before impact...had I been closer when the problem
started I may have even been able to score a "10" FAI landing (not
really-I would have gone for the grass instead of the runway).</span></font> <br>

try to see why the battery was so low, and fix the plane for spring.</span></font>
