To be honest 300 is not really that bad on a small mill like the Jatos. Though Traxxas may be wild with their estimates, I believe they would have to prove it to print it on the box, Americans would just sue if it was a blatent lie, the trading standards in the UK would be all over them here, so I would say after having my XB8 lose in a 200m drag race against a Jato that 55Mph is possible, But nowhere do Traxxas say how the car was setup on these speed runs, was it overgeared, overlean or even catching a lift on the delivery truck?

Anyway MM your arguement may have a point here but both sides have vindicated their veiws in this one, so I say why don't you go and buy one, get it running (ROFL) and speed check it yourself. Then we will all be able to sleep in the knowledge that a grand master of rc has blown apart the myth of 55 Mph.
