text: River crossing, some crawling & racing +sand bashing. I used Panther Paddle tires for the sands. All 3 rigs faced casualties, my ESC program go haywire after the river crossing, Kelvin's chassis broke slightly in front after a high jump + front shaft broke & went missing after deep swimming, D.Ong's motor stopped running after the sand bash. Only one word, EXTREME! Video coming soon.
