Mike did a great job explaining RC battery choices. The short run time you are seeing is mainly due to 2 motors, that thing must be geared down for pulling stumps.

Lipo's are great but they are expensive, you need a more expensive charger (balancing), a special fireproof charging bag and should stay in the general area in case of a problem. I try and buy my RC stuff locally but the best shop is a 70 mile round trip.

To learn more check out RCtech.net, it is bigger than Pelican in terms of free information. I buy and sell cars and parts there each year to save a few bucks.

Most importantly have fun with your boy sharing the hobby. A real bonus is that RC is a great way to teach kids about physics, machines and electricity. DP
