Vintage HotShot mk2?

[RCRod 4]

Hi all, I just got this Vintage HotShot which is in pretty good condition. I know by the bumper it's not a Mk.1 and I wanted to know the difference between a Mk.2 and a Mk.3 if there is any.

I don't have anything to add other than, ho-lee-smokes that's a beautiful survivor!!!

What are the two silver things with wires coming out???

Those are heat sinks for the mechanical speed controller, ESC's were rare and very expensive back in the mid 80's

I was hoping you would say tesla coils that fire out lightning as you drive along

Apparently the difference between an early Mk2 and some of the later ones is:

The early thing is the Mk1 floating resistors and the early Mk1 front lower wishbones with all triangle shaped holes. You can’t find these on later models anymore.
