Charge your battery to 140% using no more than 1/10 capacity charge rate. For example, if you have a 600mah battery, charge it at no more than 60mah for 14 hours. (600 * 1.4 = 840mah, 840mah / 60 mah = 14 hours).

To fix your binding servo, first figure out which one it is, then figure out what part of the linkage attached to that servo doesn't want to move and fix it. I don't know of any other way to say it, it all depends on how it's all linked up.

One thing is for sure, if you have one or more servos binding your going to drain batteries a lot faster.

Make sure you get this all figured out before you fly again.... Half charged - high drain = crash!!

Edit:

Fixed my math, "High drain + half charged = crash!!" should be "Half charged - high drain = crash!!"
