I have a traxxas rusty that I want to turn into a sand only vehicle. It is the older black chassis with rpm castors front and rear, metal geared trans, metal outputs on the rear axles, metal steering arms and castor links with rpm ball ends and a hpi savage flux xs brushless system (vektor 4000 kv and vapor pro esc). It has a stock spur gear (86t I think) and a 19t pinion. also has proline sand paws rear and proline the edge up front. it doesn't have the speed and performance I want it to have when I go to the beach and dunes. it get very warm after about 10 minutes. I generally run it on 2s but every once in a while 3s, but it gets warm on both. I want this to rip up the dunes with some impressive roosts and speed. Let me know any things to change with what it currently has no matter how small or large I just want this to be bada$$ and anything anyone can help to get it that way is appreciated.
