The problem is that most guys can't handle more power than 4 cells and a 19T in a 1/12th car. Guys up north are complaining the Stock 4 cell 1/12th is too fast on certian track for beginers.
Remember Lipo is like going back to 6 cells. On 6 cells a 1/12th car with a stock motor is faster than a Mod sedan with a 7 turn in it.
Its not a matter of guys hanging on to old technology. It a matter of guys running appropriate power packages for their cars.
