Racerx,
I have the ready-to-run Mini-x and it didn't come with bearings as I had expected also. Had to buy a set from this site (great service!) and I bought the 6cell battery pack (a must have) and then I was good to go. the car uses 2 packs of the large bearings and three packs of the small hub bearings. If you get the 6cell pack, you'll have to solder up some power leads and just solder in a Deans plug. I'm using the MRC Super Brain 959 charger and its perfect for it. Charger doesnt get hot as reported in some reviews, (at least not with these small packs). If you need any info or help feel free to ask..check out my F40 in the gallery..
