I like the clutch, easy to build and adjust. Need to sit the 4 bearings nicely otherwise you might find the clubch bell stuck after locking the end bell screw.
Fitted in an old Reds WCS M7 engine and pipe set for initial run.
Lastly, it seems that the throttle servo might block the fuel tank to sit in properly if a standard size servo is used. I will try to shim it and adjust further before changing to a low profile servo.
