Motor: For carpet, my first choice is the TX 5.0T motor, which provides a milder bottom end power, to minimize wheelspin, compared to the RX3 4.5T motor that I run for bigger, outdoor tracks. The 5.0T can be set with an endbell timing of the standard "10" or +1 line more for a bit more punch and RPM. There is no fan needed for the motor for carpet racing! As temps will rarely exceed 80 deg C.



ESC: I have attached my ESC settings. On the contrary to what some people think, lower grip conditions actually requires a more aggressive speedo setting. When you have really good grip, wheel spin is minimal, and thus, the car will move forward instantly as you hit the throttle, therefore, a too aggressive ESC setting will only be too difficult to drive. However, on medium to low grip conditions, as recently seen at the ETS, one may want to increase the timing and punch settings to help the car feel more aggressive. A bit more bottom end timing can also help the car to turn, as it will help the car to "drift" slightly out of corners. You will be able to use the throttle to steer the car to some extent!



For the best response and feel, I recommend to use a Sanwa M12S transmitter with "SHR" response mode on the CH2. I don't use any exponential on the throttle channel for modified racing!

Battery: For modified racing, these days, the trend is to go as small and light as possible. The 6200 HV battery that I am using weighs as little as ~285 grams, which gives the car perfect left to right balance. The HV battery also allows to be charged as high as 8.6V, which can be a fun feature for club racing. However, for modified racing on carpet, I charge my batteries to 8.30V cut-off, as this takes away a bit of punch, and leaves the power feel more consistent over the 5 minutes.
