Aragon,

I remember checking into them, but didn't give it much thought. I didn't think that they would work well in a truck. What about brakes and reverse.

Edit- I just went and checked them out. The highest current rating is for like 55A continuous. I don't think that it will even come close to meeting the demands of an XL class motor in an 1/8th scale truck. For my comfort, I'd prefer something that can live with over 100A constant.
