Ok just to update everyone, I bought a brand new battery (May 19, 2006). Put it on the trickle charger for 8 hours like they said. Put it in the quad. On the next day (May 20, 2006) we started the quad up, no problems, and let it run for about 5-10 minutes. So now, next saturday (May 27, 2006) we will try starting it up again. And I'll update you guys on what we find.
