Hi all
I am now chief mechanic to my my Grandsons latest hobby nitro cars which he received a Schumacher Swift 2 for Christmas. This car has been a problem from day 1 when the pull starter broke a spring which I managed to repair to keep things going, unfortunately the spring did break again but not before a major calamity occurred when the throttle jammed on and car went straight through a substantial timber gate at full speed. We have now lost considerable confidence in the control of this car and my question to the forum is has anyone encountered similar problems and what do we do to put it right. I have tested the batteries and they each have 1.4 volts + , plus I have done some running test on a wooden block firstly testing all the controls without the engine running which they worked perfectly. With engine running the servo unit seemed to have a mind of it's own when the engine was revved up it just went straight to full throttle and refused all attempts to push it back the only thing that worked was to stop the engine at which time the throttle went back to normal.
