Hi there everyone, I just got a very good power supply three days ago and I had the chance to charge my 13.2 pack too. I went to visit my relatives and I took my T4 with me and it was equipped with the super brushless setup. I went to the front street of my relatives' house and put down my truck, activated the transmitter, activated my car and it was 12:45 AM. I gave it only 10% of throttle and it went on in a moderate pace around 19-20 MPH then I gave it 40-50% throttle and it behaved like if it was running with a 10 turn double brushed motor( it was pretty cool indeed) eventually I went for 100% throttle and....MWAAAAHAHAHAHAHAHA. The speed is simlpy astonishing and to tell the truth I have not seen its true speed yet because the street was pretty short and the truck instantly flipped on its back the first Time it acelerated to full throttle and it kept crawling on its back for a meter and a half ( the truck was running without its body so I committed the most stupid thing for a first run) as a result the front and rear shock towers almost worn out, but fortunately they did not break. The truck makes wheelies the whole time and the power was devastating (not really) and the speed was beyond any speeds I've ever seen and do not think that I'm lying if I say that the truck reached the realm of the 70s mph. I even saw the rear tires ballooning to the point that I thought It was going to blow out. Now for the drawbacks: At some point the 9920 seemed to thermal a bit and it was very hot as well as the motor and I also found that the truck was lacking acceleration power as well and only after a couple of minutes of running. One possible reason could be the ESC itself and that its not delivering enough power to the motor, because the motor is a Hi-Amp version that sucks a lot of power from the controller either during acceleration or continuos running. Another reason could be the gear ratio which is around 10.2:1 ??! So what do you think everyone?
