runnaway! oh no!
so today i was driving my traxxas stampede at the park, i had tuned it up and it was running great! i was very happy!, so happy in fact i decided to try my luck on a huge mud puddle, well it turns out my car is not waterproof, my battery case got soaked and shorted, then it pinned itself ant took off! now it seems like the car had a mind of its own, it took off across the park and targeted a 86 year old grandmother with her 2 grandsons, thankfully she stoped my car with her shins, my truck must have been doing 50kph! i feel bad for her, so to keep this from happening again what can i do? i was thinking of putting a spring on the servo so when it looses power it returns to idle, any other ideas? i cant get a failsafe because it would not work if it lost all power, also i want something cheap, and i want to go mudding! how can i waterproof my car? thanks guys
