So i have a TZ 3p and it has been running great, however the track that i run on is small so i have never really streched it legs, so my friend who has a radar gun and i tested it in my mtx3 the other day, When i thought the motor was about to top out RPM it just kept going, needless to say even with my gearing for a very small track the car still hit 56mph, i just couldnt belea ve how much more top end there was that i have never used.
