On the subject of motor replacement, where do I buy 180s?
Here you go. This guy usually has them, but make sure they are 12,900 RPM. Sometimes he has different motors with the same picture he uses for "real" 180s. Great price for 3 of them.
I <3 this so hard. I've never used an Arduino in a blaster before because I have zero programming experience or knowledge on how things work. I am looking for the parts online as I type this because this writeup goes over ev-ry-thing, and makes me feel comfortable in doing this mod. Excellent work on the stampede, and even bigger props for providing a great writeup!
Edit: What battery set up are you currently using on yours?
