One of my hobbies is RC cars, actually nitro powered RC cars. I own the maximum ST car with a couple of my own minor modifications. I use the futaba skysport 6 controller. I had a couple of problems in the beginning starting us the engine. The current problem that I have is that my fuel tank wont pump gas into the engine and sometimes just stops shutting off the engine. Il buy a new fuel tank soon and get back to u on that.
