I'm pretty certain that the evevator rods are a touch longer due to a minor repositioning of the servo opening. The wing itself is now a built up rather than a foam core so it's possible the aileorn rod lengths have changed fractionally as well. In any case, some carbon tube and 4-40 rod to makke up a couple of new ones and you're good to go.

It would be nice if all the 50cc planes made all had the same control rods but I don't think anything like that will happen soon.
