I fitted the mk2 to G-IVER in 2007 before first flight,
 it's very straight forward to fit and works a treat, the few times I left it 
switched
off for the bi annual flight test just goes to show how it reduces your
workload especially doing EFATO and simulated off airfield landings,
Without doubt it a highly recommended bit of kit for very little money IMO

>> Graham, Sorry to be butting in on your debate with Tim, and I see where you
are coming from now, but can I just add that the SmartASS is g compensated so
it gives exactly the same 'margin over stall' information as an AOA device (and
at a fraction of the price). It might appear that I am pushing this as if I
had some
>> commercial tie up, which is not the case. I am evangelical about it because
we have now had (subject to confirmation in this latest case) 6 Europas lost to
stall/spin accidents, an appalling statistic for a plane that flies so 
beautifully
and is slippery enough not to lose speed rapidly. There have of course
been countless crashes of other types also, but in our relatively small and 
tight
knit Europa community it is truly sobering and we should all be asking ourselves
are we confident of not becoming number 7.
