Hi, i just did the spyder mod and linkage mod, but now the savage runs crazy. Everytime i give it half throttle it won't stop and i can't control it. It runs and the highest speed and still no response? What should i do. Also i can't turn properly. Is there a difference between the front arms and back arms and also the connection between the steering rod and to the wheel. I've got major problems and thinking about taking to the hobby shop. Any help appreciated.
