<DIV>Yes, high drain could have been the problem. Since the plane is in good condition probably you can check. I think you should consider using two batteries of your preference. I starting to use the 9100 receiver that already has two power inputs. Check details here:</DIV>

I had heard that some chargers get a "false peak" and stop charging when the battery is not really fully charged.

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.</FONT><FONT size=3> <BR></FONT><FONT face=sans-serif size=2><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

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).</FONT><FONT size=3> <BR></FONT><FONT face=sans-serif size=2><BR>Anyway I am sending the entire radio off for examination, try to see why the battery was so low, and fix the plane for spring.</FONT><FONT size=3> <BR></FONT><FO
