Hello, i am new to more expensive rcs, and i made my first a flea market hotshot. Not sure if its a mk1 or mk2, but it came with pamphlets printed in 1985 for the nicad battery. I tried to fix the msc, but it still wont work, as soon as i plug in the battery, it just runs backwards even with the controller off. There is a considerable lip on one of the contact plates. Gear boxes and suspension seem good. I am looking to simply replace the old one with a modern esc. Also, i have a new motor that came with, is there any way to make sure that its a compatible power? I will post pictures this afternoon. Thank you all.
