The Sidewinder esc is 90 amp, the MMM is a higher amp but I don't remember the exact number. I would have to look them up to see if theres anything else. According to CC this system is rated for a 1/8 rig that weighs 11 lbs or less. I ran it in a 1/10 Summit on 4s about 5 times and the fan never even kicked on...it comes on at 90 degrees. The price is not set in stone
EDIT: the white thing is a tag from the factory on the wires, theres no cuts or repairs
