The clear 4-in-1 does not necessarily mean you have the sticky collective fix. My Blade CP has the clear box but I had to do pull apart the blade grips and swap the washers around b/c I have the old blade grips. Blades with the new blade grips come with an extra page in the manual that say something about it (can't be more specific, I've never seen the page).

I have a bcp with a clear 4 in1 and the S75 servos. I have an insert sheet in my manual that says it has(had) the 3 BB upgrade(not their words)
after bending the Spindle, I think?? it only has 2 (TWO) One on each side of the blade grip with a spacer in between(brass colored) The same for the other blade grip.Hmm
