The only difference are the outer holes on the stock upper chassis. They do not exist on the hopped up part so it looks a bit retarded to have areas where something should screw onto and nothing is inserted. If anyone is mystified by what I am saying, I am speaking of the post in front of the servo mount on the left and the battery strap holding mount on the right. Those two posts are rendered useless once you step up to the woven upper chassis.

Cyclone blades fit the ends of Pro4 universals. It is the length of the universals that differ, not the end that goes into the outdrive itself.
