I have the Graupner manual and it's telling me to get 4 DS 8411's, the Wilcox manual tells me to use the Volz's in the rudder. I will have to make some measurements to see what the depth is on the rudders. I would prefer a even clean finish as opposed to what you showed me in the pictures Randy. Roger what servos did you use in the rest of the kit. I need to know this so I can get them and start my building.
