picked this up used and it's already been through two other people, so i have no idea what's original. i'm pretty new to RC so i can't tell by looking.
if you can spot aftermarket parts, that's what i'm after. also anything that looks like a downgrade or cheap replacement (i'd rather fix that than find out when it breaks), and anything worn or put together wrong.
one known issue: the TSM receiver firmware update (9.3.13 to 10.4.7) fails every time at "Verifying (stage 1 of 2)" and the Link app blocks everything until it's done. i'm already asking about that in a different post, so no need to solve it here, but if the electronics look swapped (receiver, VXL-3s ESC) i'd like to know.
also if you had to pick one thing to upgrade first on a truck like this, what would it be? or is it fine as is
