Scooter,

You'll be fine. I would recommend at some point buying a load tester for checking the batteries at the field. I use this one. Most hobby shops sell them.

Oh yea, one other thing, DO NOT leave the transmitter on without the antenna being fully extended. This can overheat the output side and seriously reduce the transmitter range along with causing permanent damage. I also would not recommend you doing it with the receiver either
