Hey there guys. Not new to RC but new to crawlers/electrics. I got this axial in a trade and am hoping you guys can help me out with some of the specs. I have a few questions. There is a capacitor on the ESC. What does that do? Also on the motor there are 3 other electronic components soldered on there. What are they for?

All i know is that it has a Rooster ESC and a Nova Motor, not sure of the size i think it is a 55t. It also has axial tires on it but i also have a set of prolines i was just seeing how the axial tires looked on it. Still need to get a good body for it, the one it came with is a really heavy plastic range rover body. Doesn't do good with that heavy body on it.

Thanks guys.
Lee
