The Kyosho spur will fit but I would run the Kyosho slipper pads and then you dont have to cut anything. (Two white pads)
13.5 I would start with around a 6.0 fdr and go from there depending on the track.
I hear there is a 72 spur that AE is going to release very soon.
which will get you there for a 13.5 but your still alittle off on the 17.5.
When your motor is getting hot but your ESC is still cold your usually under geared. If both are hot your over geared. In stock the ESC might not ever warm up so just check both to be safe.
Dean if your racing the Gyro on Saturday come find me if you need some help.
