      Well, I tested my dual battery Bit Char-A clone. And it broke my own record. It done 100cm in 0.5 sec.

      I just wish to see people post their results under this topic. Specially for people who has FET modded cars.

      Why dont you try 6.25 metres??? That is the scale 1/4 mile.

      That’d provide more accurate times for people to compare to also. starting and stopping a timer in under a second leaves a lot of room for huan error and errors in reflexes.

      True dave, i run the 1/4 mile about 3-5 times then take an average.

      Sounds like a good plan.

      How did you manage to time it and get a result of .5 secs?? obviously not a hand held stop watch?? major human error involved!!

      i measured up 1M distance. Then i setup two sensors at each end. i put the car at one end which push against the sensor which will start a stop watch once the car left the sensor. when the car hit the other sensor at the other end. the stop watch stops. i run the test 10 times and the average will be the result.

      Ok, i was gonna say, the human reflex is about .25 seconds, so thats 1/2 second for the timing.

      measuring .5sec on a .25 sec tolerance is the same as saying that an oylmpic swimming pool is 50M long + or – 12.5M.

      Not very accuract I’m glad to see some sensors where used to state such a small time scale.
