TQ RC Raceway's high grip Black carpet is the latest setup of BD 9.

It is a setting that can be quite aggressive, but it is finished to be a little understeer at the beginning of steering, so you can drive smoothly and smoothly.

If you are driving on a course with a low grip level, increase the droop first, then raise the height of the differential and lower the height of the inside of the upper arm. Although the characteristics of the machine responds greatly to these three point changes, please change it one by one so as to approximate the desired running characteristics.
