Chris,

Your statement that you flew until your receiver was getting low, about 12 flights, really concerns me. Most radios come with the standard 600 mAh battery pack. As a general rule, 4 or 5 flights at 10 to 15 minutes each will put that receiver pack out of business until it's been recharged. A dead receiver pack will ALWAYS equal a dead airplane.

I teach my students that if they cannot check the voltage of their battery pack with an expanded scale voltmeter, that they should quit flying after a maximum of (4) 10 minute flights. None have ever lost their plane from a dead battery using this limit.

I am only saying this as a suggestion since you have posted in the beginners column. I would much rather see you keep your plane for a very long time than to see you lose it early to a dead battery.
