I think it's better now. No more comms to true every 2 runs, no more brushes to solder and break-in, no more ni-mh packs that lasts 15 runs, non more cells to discharge and equalize after every run....
Now I have more time to wrench on the car looking for a better setup, more time to chat with friends and so on...
Oh, and what about 2.4ghz radios? You can turn on your radio whenever you want without the need of shouting loud your own frequency!
