Back in the 80s when i had tamiya cars they used AA battery for the receiver and they lasted for days with them, The 5 cell NiMH battery that come with these new RTR don't last but a few hours. You can buy rechargable AA batteries if cost is an issue for you. I am looking for run times. I hate batteries, I hate charging batteries for hours just to play for half that time. I want to set up the receiver to where you don't have to put batteries in it every few hours. I was wondering with this new tech how affective running AA batteries are vs. NiMH batteries.
So if you use 4 Duracell batteries and they last all day working the servos, and NiMH 5 cell battery pack only last a few hours. Then I would say the AA batteries are more affective and longer lasting. Now if you only get a few hours with 4 Duracell batteries, then it would not matter what battery setup you use.

In the end I will find out once I get the RTRs and test out battery usage and which ones will last longer. It is odd how this forum pushes Lipo batteries, electric motors, 100+ mph cars. I got a 10 year old and a 14 year old that I want to get them out of their phones and computers and get out side and into a hobby that is some what active. They don't need 100+ mph cars and hit some other kid and brake an ankle, or Lipo batteries that need supervision when charging. or a safety bag in case they blow up. I need it to be plug and play and very simple, but at the same time give them more play time and fun. These are kids.

I will get the cars in a few weeks. I will run tests on batteries and see how long each setup will last. Which ever lasts the longest I will go with. I will post my results to share with others who many have the same questions.
