These vehicles by Arrma are great cars compared to other brands at the going price. However, to make it capable of 3s and have less damage, you definitely need to upgrade many parts just to make it capable. I have had to buy an entire rear end transmission from the Granite BLX and many more parts just to make it a fun basher. The cost of it well exceeded what I expected. Keep these rtr as it is until you have enough funds to buy a proper high power vehicle.
