What was the best overall offroad motor of the 80's

[optiman]

I always wondered which was the best offroad motor of the 80's. My curiosity arise since in my childhood the "best" that I ever had was the Le Mans 240ST that came with my Kyosho Turbo Optima Mid SE. I could not afford for a better motor so I always wondered and glanced at the pretty looking Le Mans, the Trinity's and Reedy's with awe....
So for those of you who had or knew, which was the best for 2wd overall motor and the best for 4wd overall.

On a side note; Could someone confirm the release date of the Kyosho Turbo Optima Mid Special, thanks!
