Lots of info here:

Not too many suitable 4 strokes are out there for larger vehicles but OS makes a nice .26F/S which is probably what was in the truck in the vid.

Check the rc pro series rules on the displacement before you buy.

My dad is currently building a OS 56 4 Stroke into his Mugen Truggy. It kicks butt! He is still getting stuff machined but by the looks of it, it will be rock solid.

He had to have the cranked milled, have a new carb mount made, exhaust re done, all that stuff. Pretty cool if you ask me.

Anybody want pictures?

Wouldn't the weight of the motor be too heavy to overcome compared to a two stroke?

Well, were hoping the weight is not to much compared to the power. Its a kick'n power plant. My dads driving may not back up its abiltys . But he'll find somebody fast to give it a whirl!

Pictures for those who asked. This was a bit ago, there are some mods on it that are not pictured.
