My 1:43 track is in a box right now, but using a 9-volt to the braids tells me the white & red is going to be fast. The blue & white #11 seems to be binding in the gears a little and doesn't rpm up as much. That one will need a little closer examiniation.
I'll get back to you on the radius track. I have the part number out in the garage .
I bought the Porches from SCX and they are awsome . I ran them on a routed 1/43rd scale 3 lane track of fellow racer.
As far as the Carrera track , you can run your HO cars on it as well. Slip a piece of evergreen tubing over the guide pin with silicone to hold it in place. Then solder a small piece of pickup braid to the front of the pickup shoes on the HO . Good to go .
thanks gonzo,i have a couple tyco pros i would be interested in using,but the connections...well you know how it is
one more thing have you guys ever done a guideflag conversion on the carrera go!cars?i really enjoy my little artin porsche,but i think a flag would improve the performance,and my f1 carrera cars look unrealistic in the turns at best.
