CrazyAl,
I stand corrected. The Mirage drive will fit in the hatch of a Revolution with Regular or ST fins but not the Turbo fins if you have the cam lock system. The Cam screw posts keep the Turbo fins from going in far enough to fit the entire drive in the hatch. I do not know about the click & go system. If the click & go have a support that extends to the bottom of the hull most likely the Turbo fins will not fit in the hatch either. But there are alternatives as I mentioned.
You can set you mirage drive a few ways to be out of the way.
#1) standing the drive pedals down and bungee. The pedals fit nicely into the foot wells.



my back to back padeyes from inside hatch with cassette leashed. Swim Noodles for positive flotation.

#2) Lay pedals across hatch with fins vertical between legs works like a charm. I just did a 7 mile kayak tour and decided to paddle half the trip and this worked exceptionally well. I even forgot my bungee and it stayed put but I was on calm waters.




Hope the photos helped
