I ended up taking the DT-03 Neo Frog to the rugby pitch to see how the sand tyres would work on grass like I said I might earlier. The tyres worked great, gripped well in the grass and gave good traction. No problems there. But I had a strange issue return that I thought I had eradicated. The ESC I use is a Hobbyking X-car 120a. The receiver is a simple 3ch Flysky. The problem I'm having is that the range is poor and the further away the car gets, the more throttle lag there
