19mm hex?

[mr. ed]

I've bought some parts of an old kyosho: inferno dx and plan to do an electric conversion along with building all that's missing.
Now, it has 19mm hexes and I know17mm is the standard today.
But are there others still today using 19mm hexes? I've read stuff about an older duratrax but believe that's more of a monstertruck thing, and think I've seen a mention for an HPI Vorza???
