Its been awhile since I've had a RC Car, I currently fly electric helicopters so getting back into cars will carry some questions from me. I do have my b4.2 coming today and look forward to building it tonight. No electronics yet, those are still being thought out. Thanks for all the help guys.
Actually that is more of a safety issue as to why they only put small amount of fuel in a drag car. You don't want 20 gallons of gas in a car if there is a fire. When I use to drag race my 70 Chevelle I made sure the tank was full for extra weight over tires for traction. The reason for running less mah packs or shorties is do to weight. You don't want to heavy of a buggy to race with. The shorties you can move around for weight bias. Lot of times a higher mah battery wil have higher c rating also. Which is more important for stock racing. Lot of guys running mod will run lower c rated batteries to smooth out bottom end.
