    Track Power

    The series will be raced at 12 Volts.


    If it is not mentioned it is not legal.
    These rules were written to create a fair event and not for racers to look for loopholes.

    Model list
    If you want to run something I missed please let me know and I will add it to the list If it meets race rules.

    BSP* is fielding

    — NSR McLaren  (fantasy livery)
    — Racer Ford GT

    I will be posting an Un-boxing page soon.  The Racer Ford GT is 90% cool, very detailed, lite well built.

    CONS:  No lower front axle adjustment hole and not much “meat” to drill some with a M2 Tap.

    17k long-can motor – certainly is going to be replaced.

    I’m considering running the Slot.it Nissan GT-R (CA49),  it’s not on the list, would this be eligible?



    Avatar photoporsche917

    Jay – I’m not the official series manager but the Nissan GT-R is a full on GT3 car and will be allowed to race.  That is one of the best looking Slot.it cars I have ever seen.  Don’t hesitate to reach out if you need any help getting it set up.  I would love to see that car run well in this series.

    This coming Saturday the 24th is the first round of the clubs GT3 series.  This round is happening in Q3 due to the constraints on the clubs Q4 calendar.

    Looking forward to seeing everyone and their shiny new GT3 cars.

    Well at least you didn’t wait until the last minute.  🙂

    Slot.it actually has the Nissan and a Maserati GT3.

    Our first vacation in three years got in the way.  (CO was amazing, by the way!)

    Fortunately, I have a bunch of tires already glued/trued from Nationals.  So a bit of motor break-in and balancing and I’ll be at a good starting point.

    I’m going to need a ruling on liveries regarding numbering. The presentation liveries only show two numbers.  The rules say three must be visible.  I can stick another number on the car, but it defeats the fidelity of the original livery.

    what say you?  🙂

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.
