Nobody is arguing differently. It is just that the stock losi's are no where near as bad as he is describing and there is no way buying new tires is going to shave those kinds of seconds off his lap times. Reading a driving theory book and planning out the lines through the entire course to maximize straight away and cornering speed will drop seconds off his lap times when he adds throttle management and handling adjustments into the mix. Furadi has a great suggestion. Too many people blame the hardware and buy the latest upgrade to try and make the Amain. What it normally does is get them a car that is a overweight and a wallet that is underweight in the Cmain.
