Completely agreed with 75 being unattainable with a TT motor. Just looking at its part-quality, its pretty cheap. NO ONE runs those tires on a touring car.
As well, only high-end (ie. $300+) engines like a few of O.S.'s .12, a Collari, a Nova Rossi, just to name a few, are capable of speeds that high.
Unless you have pics of the hobby shop dude's "machine" that read 75MPH, as well as pics of how this "machine" works, I'm calling BS.
No one tests the speed of an R/C car using a "machine". Any reputable source of R/C speed collecting is done using a GPS radar.
