Yes I have been looking at the Dittel KRT2 but I am slightly concerned about the size of the digits shown on the display and also what it is like in bright sunlight under a full canopy.The view of someone who has actually flown behind one would be good.
My own thoughts at the moment are that the Funkwerk may be a better bet for a couple of hundred more. Not the OLED version which I have seen is only very average in bright sunlight.The LED version is better in this respect.
