Lipo Battery for starters, put one in my Traxxs Rustler, thing is an animal, clocks over 100 clicks when I can keep the thing in a straight line. (might have to get the quick cut saw and cut myself a few slots in the road )
Lipo lasts me about 1/2hr flat stick running and takes about that to fully charge. Just remember when not in use to store your batteries at half capacity to avoid damaging any cells.
RC's are great fun, even more when you can con a mate into buying 1 too, thats how I got sucked in, My mate pulled his out in the pub carpark after we downed a few cold ones and after about 5 mins running into things I was convinced to buy 1
