Did anybody ever compare the behaviour at low g of the Spit and the Hurri? My impression is that the Hurri is less sensitive though still quite sensitive.

I too think it is a bit overdone. The slightest dip will lead to a significant performance loss.

I do understand that when you carefully push the stick this will reduce the lateral g from 1g to something like let's say 0.9g or 0.8 g which will lead to reduced hydraulic pressure at the fuel outlet of the fuel tanks hence reducing the fuel flow hence leading to a leaner mixture. Cut-out only should happen when the total pressure at tank outlet (including hence the hydraulic pressure) is equal or less to the necessary pressure for combustion in the cylinder heads plus the pressure losses in the feed lines. Pressure losses are a function of fuel flow and decrease with decreasing mass flow rate as the flow velocity decreases. I though do not know at which g this could happen.

Up to now I just wonder why there was no mechanical blocking of the forward movement of the stick as even levelling out from climb is extremely tricky.

Just to get me right: If it was historically this sensitive I wish to keep the effect. Currently I have some slight doubts.
