That beast of a servo is the JR 8711:

I love the look of the plettenberg, don't think the heat sinks are as functional as fins, but the built in fan helps I'm sure!
As far as the arms go PAINT???? LOL They are dyed, but I cannot take credit for that, as I bought them that way. Now I want blue arms, to match the pletty but I am torn between the nice look of all blue arms and the extended wheeelbase Traxxas rears/black RPM fronts.
Any thoughts gents??
