Brushless hpi baja rc-monster

The 1527 is working rather well, actually. I did get it up to around 170 degrees after a while(running 7s and 8s packs), but I was running mostly in the grass and was being quite aggressive with it. A heat sink and a fan on the motor will be plenty of insurance, but probably isn't necessary. I am quite happy with it, actually. The shaft is too short, which is compounded by the motor adapter I had to make to install it, so i initially had trouble keeping the pinion on, but I have a custom adapter/bore reducer on there now and it held up for the last hour or so with no trouble.
I have the 1527/2.5d motor installed with a 12t pinion. the motor has a 5mm shaft and is only .75" long, which only allows about half of the pinion set screw to engage the shaft. The custom adapter adds another set screw and is working rather well so far. :)
