My Hudy pancar station works fine with my Serpent. I found some bearings that fit into the bearing holders. It was a tight squeeze, and I can get them out now. I have an extra set of holders for my 12 scale bearings. I just swap out the holders depending on what car I run. I also use an extra bearing on the axel as a spacer to allow the wheel nut to be tightened on.
