Impressive..can anyone confirm how this 5-port tz runs?? Willing to change as I know the os is cheaper too...
I ran a tz 5 ports against my friends rr12L5. It was in a parking lot. The distance was about 10 times the width of a parking space. His acceleration was faster, but at the end, we were pretty much even. Also, it depends on the setup/gear ratio/etc.
