Writing about the Tamtechs just gave me the idea to measure the timings as compared to the mini-z. My living room track is small, it is a L shape and a complete round measures 30ft.
For 10 rounds my 2 mini-z (GT3 and Modena) made it in 53 seconds.
The Tamtech is under 46s and still improving!!! thats more than 2/3 second a round
