local hobby shop or Radio Shack will provide batteries ranging
from 1000 mAh to 3000 mAh, this means the 1000 mAh battery has
only 1/3 of the capacity of the 3000mAh battery. The R/C model
"Great Laker" is powered by two Radio Shack 7.2 volt
3000 mAh batteries. This gives the model a very long
running time of about an hour.
