I noticed on a posting somebody was asking how the pitot tube was fixed.
It does not rotate with the spinner, it is bolted to the engine housing. I have taken a photo on my engine (the one that is waiting to be fitted to my RV-12 when I can extract all the kits from Van's) The pitot tube passes through the hollow gearbox shaft (shown by the red ruler) and is bolted on where the pitch mechanism or govener is mounted if needed (shown with the arrow)
