top shaft pin

For that price the old 8-9XL feigao & MM esc with a good ubec and 4s lipo would be much more powerful with the ability to go much faster and still run reasonable temps. It is pretty much the 1st BL setup most people run, and is a proven setup- the 9XL will run cooler on 4s, and if you get a better esc down the road, it will also be good on 5/6s with sensible gearing. The HvMaxx is limited to 4s/14cells maximum, and is much more fussy about gearing, especially in a heavier truck, but still does fine in a light truck (9lbs or so).

The rollpin will break. Its really weak. I first did the allen key trick, but it eventually sheared. I then used a drill bit that was slightly larger, can't remem what size (was a fractional tho) and had the best luck with that. For the drill bit, I drilled the hole out w/ it, then pushed it thru. I bent/flattened the ends a bit to keep it in place. Since this solid, round, hardened tool steel, I think this is the strongest option.
