    TUNING NOTES
    MOTOR – At the series voltage of 11v, some people testing Vettes are experiencing the 25k motor to be “too-hot” (jackrabbit hops and fishtails); even with Low gearing (e.g. the OEM 32/11 = 2.91 ratio, or 33/11 = 3.0).
    Conversely, the 22k or 21.5k motors may need Higher gearing (2.82, 2.73) to go below 4.3s.

    BALANCE – the nose on the Vettes are light, so some weight behind the guide (~3 to 4gm) or on the nose of the motor-pod (~ 5-7gm) may be something to experiment with.

    At 4-years old in Pensacola I repaired my steering linkage on my Ford Pedal-car. Dad later converted this car to a Blue Angel with ailerons and elevators with a working "stick/yoke"; the rudder was controlled by the steering wheel. I like all motorsports - I grew up going to a NASCAR Feeder track with Sportsman and Modified classes, and was lucky to attend drag races in 1970 at Orange County Raceway. My first solder-iron was a Christmas gift at 9yo; I modified T-Jets to be AFX spec before AFX Cars were in local stores. I rebuilt a few tractor & car (SIMCA) engines plus transmissions by 15yo (I still have my ring-compressor and valve spring tool) I am a former mountain and road bike geek & perennial sound engineer.
