The Team Associated TC4 still a very popular choice for VTA racing and any others kinds of sedan racing. However, the chassis was made to accommodate NiMh packs. Since, nobody runs NiMh anymore, we need to slightly modify the chassis to fit new LiPo hardcase battery.
The modification is not difficult, all you have to do is to sand the little plastic tabs in the battery box. All you need is a Dremel equipped with a sanding drum and 5 mintues.
Once the tabs buffed, a hardcase LiPo pack will nicely fit in the battery box.
