thanks guys gives me a few options to look at. I have no idea about batteries eg/ what 5000 mah 40 c and have not had a rc car for 22 years and am keen to get into it with my son. My inlaws are travelling to the U.S in afew weeks so i am hoping they will pick up some gear for me there. I am sure in time i will have a better understanding but i want to take advantage of some cheaper prices while they are there. thanks for the help.
