High Motor RPM
Is the least of your worries concerning chip capacity: as the RPM rises the Amp draw drops.
I think that we can safely say that 99% of the commercially available 1/32 plastic production motors will remain well within the 3amp cont./ 6 amp peak range that Slot.it specifies for the 02 chip.
There might be cases were cars run with extreme amounts of "magnatraction" will approach these limits, but I expect the motors to burn out before the O2 chip does
In general 1/32nd PP motors don't use proper springs to push the brushes to the comm but little strips of metal.
As high Amp's are drawn the resulting heat slowly kills the springrate of these strips and reduces brush pressure resulting in less torque.
Yesterday we were back at our club and tested the O2 chip in one of our 1/28 Kyosho Gr C's with a metal PN chassis.
Weighing in at 172gr (twice the weight of an average 1/32 Plastic production) we ran the O2 chip with the ProSlot Euro MK1 with 25,5 x 13 Scaleauto Procomp 3 tyres on a grippy Carrera track....
Without any problem
So to add to Gary's list
Slot.it V12/3 orange endbell
Slot.it Flat 6
Slot.it Flat 6R
Pro Slot Euro MK1
O2 Power supply
On a different note, as the cars are no longer restricted to a specific lane
your power supply might be an area where you could experience capacity problems.
Even on home tracks with six cars drawing 3 amps each at full power under full acceleration (6 x 3 = 18 amps) and you can clearly see where you might need an upgrade to get the max power out of your motors
with kind regards
