Hi, I am very new to RC cars and even newer to touring cars.
I have just built a T4 '15 with the following equipment in it:
Orca 17.5T TX series motor Orca Vritra VXX Competition ESC Savox SC1251MG servo Wolfpack 25C 7.4v 37Wh 5000mAh battery Pinion gear 30T Spur gear 84T
My two other RC cars are an XRay XB9e and a Losi 8ight 3.0
When I finished building the T4 I was expecting that it would blitz the other two off-road cars and (admittedly they are using 3s and 4s batteries), but to my surprise, the T4 is a lot slower. I strapped a GPS on the back and got a top speed of exactly 40kph. I have not done that with the other two, but I know just from driving, that they are nearly twice as fast.
I have not adjusted my ESC and it is still running in blinky mode and I know that I could get the car faster if I adjust it, but what I am surprised by is that even after 7 or 8 minutes of 90% full throttle, the motor is only just warm and the battery, is stone cold. It suggests that I am not getting adequate voltage.
Can anyone give set me straight? Is this normal, or is really slow as it seems to be.
Cheers, Al
