In this gallery you can see the collective and the two engine throttle installed in the simulator. Since Stephens cockpit is designed to be modular and for dual use (Helicopter and (GA-,Jet-,Prop-)Plane), he had to figure out a way so both will fit in and work togther nicely.
This picture shows the collective (with the throttle unit taken out).
Stephens friction lock mechanism for the up/down movement of the collective.
And with the throttle unit installed. It hides the collective, so the only removable part is the throttle unit. The collective box is always installed.
Here's the two engine "quick and dirty" throttle unit.
Where it fits in with respect of the whole cockpit...
And the throttle unit module taken out.
