Tex, the Fiorini clutch is no more adjustable than a stock Revo clutch or any clutch that requires the changing of springs. Additionally springs lose tension over time and there is now way to compensate like this new clutch.

Oh yeah, I know you questioned the user friendly aspect to this clutch, see those two little holes on the nut? There's a tool that fits over that to adjust the clutch while still in the vehicle. Super Easy!
