Vad,
The Dominator slipper clutch system is not a direct drop-in. I am having a "doubler" plate made so that I can drill new holes to mount the "complete" slipper clutch system. Then the doubler plate will be mounted on top of the Hyper 7 chassis. The "complete" system includes the plastic mounts, aluminum spacers and standoffs for the Dominator. All of the parts are available at Tower Hobbies. Part numbers: 18011, 18012, 18161 and 18987. The 65T plastic spur gear is: 18163
65T Spur Gear I will post pics when the doubler plate and motor mount are finished.
