DUH figured out the pins in the hex nut adapters! Guys any secrets or tips you have I could use I am a motorcycle and gocart mechanic, just learning revo and hellfire mechanics. I am gonna put a 15t clutch bell on and aluminum clutch shoes, with gold springs. Anything I need to know before I do this? I am also putting a hitec titanium geared servo in and putting different differentiasl fluid in any advice would be appreciated!
