oh ok ! it takes some jumps to get the right reflex : correcting the balance ( throttle , brake , left, right ) to correct the balance of the car if needed

i would advice you to start small and get your way up. try to land on a softer ground first : tall grass, sand, pile of leaves

your Arrma Granite 4x4 BLX 3S and Arrma Outcast 6S are ok right out of the box. you can start with them stock. as you go bigger you can modify them
