I would look at the area of the chassis in-front of the guide. Is there enough space for the wires without fouling the body work?
If you place LED sensor in front of guide then Standard ARC and unmodified APB will not register laps.Thanks Greg,
I should try that. I was wondering if there would be any lanechanger-probs because the sensor is Not in the designated position. But trial and error is part of the game anyway.
Not necessarily, you could remove the magnet and run on a lower voltage, about 10/11V should be OK. If you do find that the chip fails, the cost to fix it is the same as uprating it .......Good point Greg. So I better switch to some smaller motor. My track is only a small 15meters. So the yellow big block may be too fast anyway.
