Here are the prototypes of
* Optional spirit level at convenient to view position.

The level is clamped to Rotator D4. It extends out of the R1/10 and can be placed to any easy to view position. We will also make similar level for monopod.

* Optional advanced rail stop to remember NPP setting.

This is a compact and elegant integrated stop plate. It is clipped to the lens ring plate. The stopping position has to be predetermined and machined in the factory. The mounting of lens rings has been proved to be very repeatable. After collecting and varifying the setting for a particular lens at a particular tilt angle, we will start making the stop plate.
