RE: Batteries???
A good lipo from HobbyKing is about 20-30 dollars. An amazing Accucel 6 charger that also will charge your Nimhs will be 25 bucks. It has balance jacks, so no balancer is needed. A power supply, you can buy one from HobbyKing, or buy a PC power supply, thats 15 bucks. A soldering iron, thats 10-20 bucks. Dad might have one. Some connectors to solder on to your battery and charger, thats 5-10 bucks.
The ease of lipo learning, thats priceless.
